Biochemistry

It is Clearly clearly Clearly clearly Clearly clearly Clearly clearly

I loved this lecture! Everything was so well explained: simple, straightforward, and I especially love few external tidbits thrown in such as the meteorite portion. It helps to remember these facts. Thank you!

This lecture was one of my favorites as it made something so confusing perfectly digestible.

Dr. Ahern is a very good lecturer. He explains concepts very clearly.

This lecture provided me with so much clarity. Thank you

aa a aa aa aaava aaav aaa aaa a s s s

Excellent resource. Thank you. I also enjoy the quizzes and practice medical scenarios.

He explains on a perfect and short way making it easier to understand

Wonderful, simple and easy-to-understand video. Finally got it

This video has several problems. It does not seem to be a continuation of the previous ones, it has unclear information, the reparation itself is not explained, and the name dropping doesn't help either.

The best explanation, Concise and to the point. Thank you so much.

Excellent review of the basics; been a practicing Doctor of Chiropractic for 27 years and your videos are bringing it all back again! On the way to taking the MCAT to get my medical doctorate in Pediatric Neurology specializing in neurosurgery. Planning on beginning practice when I am around 68/69...my second career. Thank you for helping me do this great endeavor!!

Love this lecture. Dr. Ahern explains much better than my professor.

I FULLY recommend!! Definitely has help out in my courses.

Five-star score not only for the high-yield information but also for the excellent teachers, spaced repetition tests and articles. Thank you all for bringing this amazing learning format!!

best explanation of the iron transport on the web that I have come across. Good clear diagrams.

They give clear explanations on all topics in such a way that it is easier to grasp. I personally enjoy learning more about a particular topic and Lecturio is the perfect platform to do that as well. I highly recommend Lecturio to all students for better understanding of relevant topics.

Really good explanation. And I like the professor. I understood

Thank you so much This video helped me so much en my sesions of study

Please is important to add more clinical correlation, clinical cases and bridge to other areas: pharmacology, microbiology, etc. Usmle test the integration of knowledge.

Comprehensive, latest information presented in an easy to understand formats. Thanks!

Interesting. I have tries to learn this about 2-3 times but never quiet stuck in my mind. Too easy to forget why an enzyme does this or that, however Dr.Kevins way of sharing the WHY this is significant really helped conndct the dots.

Interesting. Mental thirst quenchinly good. Interconnected. Just enough info. Dr.kevin fun lectures.

I really appreciate how Professor Ahern broke down this topic (no pun intended). He does a really good job at tying things from other lectures together really bringing these pathways together while also trying to enrich our understanding of the context behind em. Thank you for your hard work!

I honestly had a lot of fun listening to Professor Ahern. You can tell he is really passionate about Biochem. I learned a lot. Great course if you're interested in understanding aspects of the metabolic pathways conceptually while appreciating the details/context that enrich your understanding of them and how they are interrelated.

ok. could use improvement please include that Kinesin and Dynein are ATPases that use energy. also that only Kinesin is displayed here. I was so busy looking for Dynein information, that Kinesin info went out the other ear. This could be better by improving the diagram.

I liked the way the R and T states where explained. It all became very clear

This course is an excellent presentation of biochemistry. Professor Ahern presents the material in a clear, concise, easy to understand format that is easy to follow. I really like that I can pick and choose the lectures I need to watch, particularly those that I need to prepare for my upcoming exam. I find the review questions very helpful. Overall, I am finding the course very helpful and I am looking forward to completing more of it.

I like that Dr. Ahern's way of presenting the topics is informative and does not make me sleep. Usually, our classes make us feel drowsy because of too much information. It helped me understand the concepts more and I was less distracted.

It was easy to understand, and some details, which i think was enough! not too much information, but enough

Thank you Dr. Ahern for this very comprehensive lecture. Going through the biochem book makes this topic very complicated. It is amazing how you can simplify this topic to get to the point and what we actually need to understand.

Difficult to memorize all pathways I think it could be more interesting

I love it! It's clear and concise! Dr.Ahern is a gem to learn from. He breaks it down to where I can understand.

Nice speaker and illustrations. The lectures were engaging. Thank you!

Really good divided and explanation, with good examples and great review questions

Comprehensive course with exemplary format & teaching style to explain core concepts.

Aminoacid metabolism Is not easy to understand but still good !!

fast confusing order of explaining Its not like it simlifies anything the way its explained is quite fast and confusing very mono tone

Kevin Ahern is a really good teacher, I really enjoy his lectures, but sometimes it's hard to follow the lecture due to the presentation picturing one thing and him talking about something else. And also when he's talking about about the presentation I wished he had some sort of pointer so I would be easier to know what structure he's talking about????????

Professor gives a very clear explanation, easily understand. Thank you.

Beautiful and very good explanation . easy slides. thankyou. study matter also provided

The presentation is very nice and helpfuly The organization of topics was very good

I'm impressed with how high yield the information is. The professor touches very important aspects in just the shortest time that one video has, and that is really impressive. I do have a degree in Biochemistry and molecular biology and so this is really making me master the course gradually. For sure I'm recommending this course to my friends from same college already who aspire studying medicine like me.

It was hard to understand It could be better another way to explain the topic

The videos are shorts and specific an also great explanations

Really course is wonderful, and very useful and Professor has easy and simplified explanation of most of the complex topics in biochemistry.

Great explanation with great examples . Knowledgeable in subject matter , content up to date

THE TRANSLATION IS NOT CORRECT, THERE IS NO CONSISTENCY IN THE SENTENCES

Thankyou so much for the opportunity to relearn most of the important and key concepts related to this cornerstone foundation to Medicine & Life Sciences! Wish I had this tool in my undergrad days!!

It was a great lecture, I learn a lot. Thank you Prof. Ahern.

He is the best here , I swear Idk but I like him

Its excellent because there is more physical and clinical correlation and enzyme mechanism simplified

Great course for introductory level biochemistry. Prof. Kevin Ahen is a great teacher, knowing not only the topic but it's historical background...

I noticed that there weren't any lectures on mineral metabolism in the library. I think students would really appreciate it if you made a module on this topic as it has a lot of biomedical importance and some relevant diseases are associated with it.

He's a legend ooh I don't know what else should I say to complete 10 words

biochemistry was tough as I havent chemistry before. Had to keep reviewing, loved the tests and course presentation and so satisfying when i got the answers right. Great system for people like me . cant wait to do other subjects when i finish this one.

such a hard concept explained so easy and well. such an amazing work sir

La verdad es que es muy buen curso, el ponente explica demasiado bien y me gusto mucho qué hay actualizaciones

what an amazing lecture god bless u sir and i wish to meet u someday

Each and every concept is explained with each lecture it has helped me in getting to know things well rather than just learning.

Thank you so much; Nonetheless, i really need to let you know your vocabulary is above my reach

Great explanation about the Bohr effect, thank you very much doctor

I understand very well, thank you Professor Kevin, these help me a lot

Dr. Ahern pointed out very interesting aspects like heat generation/high energy of PEP and the 2,3-BPG production. Maybe I wasn't paying attention the first time I learned about glycolysis, but this extra integrative information it makes this step easier to remember. Actually, in generally, these human focused biochemistry lectures, are easier to digest, since when I learned it originally, it was mixed with plant and microbial biochem.

It was much needed review for me in general. Thank you.

Enjoyed these videos very much. They helped me understand concepts I was struggling with.

Great work here,,, I’m so happy for the clearly understandable English

The lectures on Enzyme and Enzymes Kinetics were thorough. There were detailed information on some important concepts.

I just find the need for an extra time revising this, particularly offline. I always find my self making some notes unlike Anatomy!

Prof Ahern explains very well & makes the key steps/enzymes memorable (eg PEP is full of pep!)

So good explications with a nice and simple way . I really appreciate your effort .

I think it’s too fast, and not with details so please correct these problems

Magnificent lecture about polysaccharides and their functions for storage and release

The video highlights the important concepts about the hydrophobic amino acids group

The lectures are very thorough and give good details about what is high yield.

I love the way he explained enzyme.... A brief and easy to understand lecture

Thank you Dr. Kevin Ahern. You made me fall in love with biochemistry.

I really liked the explanation, finally after 2 years, I understand this!! Thanks :)

I always enjoyed Dr Ahern's handling of the Biochemistry subject, especially his eplanations

It's is just good that's why 4. I dislike that it's doesn't explain clinical too much

It's okay.... But somehow hard to comprehend. I will love if you can make the teaching much easier to grasp.

Every slide has been clearly explained in detailed form. Thanks sir.

It's unfathomable how much this lecture has saved my time. Though I would appreciate a quick-summary of the products turning into intermediates for other cycles. Like with how g-1-p turns into g-6-p

The lecture simplified glycogenesis to extreme simplicity. It truly helped save around 30 minutes from my lecture, by providing adequate information

this is amazing thank you , i gained a lot of info about viruses that i have not know before

very clear explanations and the questions helped me understand the content

It's good, informative not as detailed as I need it to be but it's a good framework to build on

this video is short and easy to understand. Thanks Teacher

Good explanation. Pretty bad diagram. Animation probably would work better.

First of all, I like the depth of this lecture and Professor Ahern is clearly very knowledgeable and concise on the the topic being discussed. And I also like due to the fact that this video is clearly a high-yield resource which is very helpful for my upcoming medical exam. However, I believe that this could have been better had the previous cycles preceding the formation of OMP explained as well in order for us the students to be able to get the essence of the information better. That's all I have got to say

Me encantan las clases son muy explicativas y muy detalladas , simplemente excelente!!!

Excellent Lecture from lecturio; I highly recommended for students from medical school. It is an excellent learning platform.

i enjoyed every second of this video and it opened my mind to study more and become what i have always wanted to be a radiologist

I love lecturio, it's the best app in the world. Lecturio has everything you want and can help you to be the best in your class and also be the doctor you want. Lecturio is an opportunity that can give you the change of your student life.

Concise and clear; exactly what I needed for this topic, thank you.

Good amount of detail in digestable amounts. Very much appreciate able to run the videos at different speeds.

No explanation at all just reading , sorry for that , No interaction

Very good review .enjoyed the enthusiasm. Visuals were ok but not really understood.!

It's great to learn from someone who's enthuisiastic about their specialty and even better at teaching it. Thank you Dr. Ahern (:

This lecture is amazing and I loved the explanation regarding the conformational change of hexocinase during the reaction.

His explanations are very good. Biochemistry made easy!! He is very good in teaching.

beautifuly explained. thankyou!! Every point in every step was explained nicely.

I like the short videos. They described what’s important and later you get questions about the video.

I love having access to such rich learning material, thanks for making this an available resource. My only criticism would be that the quiz questions could use improvement and the professor could talk slower to make note taking easier. Overall, very grateful to have found this!

Teacher speak slowly to help me understand Glucose in my body

rate of speech is good and i understanded the subject he explains it very simple

me gusto muchísimo lo recomiendo a todo el mundo que quiera saber mas

Understandable!!! Easy to remember! And pretty useful!!! You really need to learn basics topics in Med career it surely make you to be highlighted over another students

It helped me clarify some topics I had been having trouble with.

Sorry, the following videos have the information that I was looking for, sorry again

Amazing way of teaching, compact and efficient. Really good job, keep doing it Mr. Ahern.

Has high yield infos which are not in other lecturer's lectures

I really like the video, makes medical biochemistry easier to understand

My professors at university failed to explain lipid metabolism in an understandable manner. Prof Ahern does a great job in explaining complex topics and I am really grateful for that. Thank you

I loved it, really interesting and easy to comprehend, thank you very much :)

Need more mcq 's for practice and good content. Very clear concept s

Very good Thanks Really it doesn't take much time and its really good

the lecrure is detailed and very comprehensive it is well presented i also liked the quiz that comes afer the lecure.

Excellent breakdown of key topics and very easy to follow.

It almost always fails to explain 'why'. These lists are available in any textbook. I was looking for an explanation to understand it. Also, visually it is looking at a table for 5 minutes, pictures could have explained better.

Before Lecturio I struggled with comprehending the mechanism of proteases and enzyme kinetics. Dr. Ahern brilliantly & easily explained these concepts in less than 5 minutes. I am currently in a graduate program for Medical Sciences, we have cumulative exams every quarter & I was just memorizing the info but now I finally understand. I recommend Lecturio to pre-meds, MCAT, and Med students.

Kevin sir explanation is very very nice and it's an extraordinary talent and explanation but little more information should be presented in power point slides so that we can learn more and more by step by step .. Thank you sir From Sanjeev India

Dear sir/madam In regard to the Biochemistry basics,I am much satisfied by the cours.In fact,the videos concerning biochemitry basics are well summarized and are full of useful information in the regard of médical studies.Because of this,I am enjoying the course and continuing either to learn much more . Yours sincerely Asher Hategekamungu

Dr. Ahern is a fantastic lecturer. All the course is simply awsome.

Dr. Ahern is a fantastic lecturer. All the course is simply awsome.

The course was easy to follow and has good illustrations of the concepts. I also like the quiz portion of the course.

this presentation was good and the way sir explained the concepts was nice

Great professor and easy biochemistry topics to learn with good explanation.

I work in a large public hospital biochemistry routine department, when I studied this subject there where no computers, only text books. So this is a refresher and update of the subject. I am enjoying this 'new' way of learning and it enhances my work knowledge as understanding theory is important for performing work well.

Whenever I get confused about a pathway, I come to watch these videos and it helps tremendously. Thank you for what you do.

VERY clear explanation of how this works, I love Ahern's lectures.

It is an xcellent explication! I understend it at all. Thank you

I like his style and respect his effort. I've been using these lecturers to review my knowledge

I find the teaching style to be effective and well planned. I use lecturio for supplimenting the topics taught in my classes

Very insightful and brilliant explanation. I learned very much in this lecture! School professor just skip much of the importance in PPP!

hi Biochemistry's videos are interesting and give me information, the orator pronounce correctly. As you know I do my best to prepare ecfmg exam and board examination next, of course after having sufficiently training and advices under your guidance I would like to apply ecfmg examination this year, now would you please give me more information for preparing step one and step 2 exam.

Excellent lecture, well explained so I could understand it. So important to understand and not just memorize these topics.

Excellent lecture. Understood Bohr effect better than ever. I love these lectures.

This videos are amazing, the professor is excellent and his explications are clear

He is a very Good Teacher as he teaches as if he was narrating a story.

Thanks Mr Kevin for your time, dedication and preparation, blessings my man!!! happy 2020

The Professor is excellent, every one can understand easily de concepts

Amazing explanation made me understand the concept clearly in a short time

It was so enjoy to understand the biochemistry and the teacher was so great.

Excellent teacher . Great lectures . He knows how to teach the subject matter

two stars just for the effort. But its ore like reading fro book. Nothing different. Very boring. No interaction.

Great professor. Has almost everything needed for my course in Biochemistry.

I was struggling with this subject in school and he explains it so thoroughly.

Talks clearly and explains all the key points so that you can understand the lecture in simple terms

Just on the point, Lecturio is what they say it is. Thank you Lecturio!!!

The topics were categorized and explained well with good examples

Studying Biochemistry lectures helps me to understand and hold in memory every each case,,, so this is the best ever

Muy buen docente, se nota que le apasiona su profesion y la ejerce con entusiasmo.

I love it... 100% worth it... Made it simple and easy to understand!

A huge thank you to Prof Ahern! You explanations are very easy to understand and your lectures are a huge help to get a better understanding of biochemistry topics. Thank you very much!

I like Dr. Ahern's lectures, I think he is the best in this program. He's very straight forward, precise, concise and connects different points related to what he's talking. After seen these videos I went ahead and did a q-bank of a different program and nailed the ones related to this thanks to his lecture. Some people need to keep in mind that these lectures are not going to cover every single detail, but unlike lectures from others study courses, they do cover more than the basics. For broader information with specific details you definitely need to read textbooks (e.g. Guyton, Robbins, Harrison's) and " google" it up.

appreciate very the mechanism described in this lecture. Very informative and easy to understand

It’s not a bad lecture but it’s bulky stuff that isn’t simplified to hold ones attention, don’t get me wrong, it has its highlights but it could be more interesting.

Really good discussion. I would love Dr. Ahern to by my mentor

The DNA Repair lecture was not very clear at all.

It is a great parsimonious source for understanding the mechanism in which amino acids build into protein and how amino acids are broken down through metabolism into various molecules inside the body. The lecture also provides the structural frame understand the basics of amino acid regulation through metabolism.

The explanation is cristal clear with examples and illustrations. Good picture of ARN structure.

All the explanation are precise to the point...and covers all the important concepts

Dr. Ahern creates a great foundation by breaking down concepts and building on them throughout the lectures.

The professor is excellent. I like how he explains things. Some of the professors move their arms around a lot which can be distracting or spend the whole time looking down at the computer. With others it feels like all the do is read from the slides. However the biochem lectures are very well done and by far my favourites so far.

Thank you for your knowledge and for spreading it in this way for us, the students.

I couldn't follow this lecture - it was not presented well at all.

The lecturer makes the topic interesting, easy to understand. One begins to appreciate how these things link with everyday human existence and how they play a pivotal role.

its good and thorough, also covers minor lipid types! good to learn

Simply explained with a little history that made it fun and also helps keep the connection to the content, So much of medical knowledge is facts and figures which can easily become blurred in my mind. The connection to history helps this content stand out in my head! Thank you!

Explains it completely from the start to the end , everything is clear and simple . The structure is very easy to understand.

Dr. Ahern, I appreciate the pharmacological and pathophysiologic connections you make when delivering your lectures. It aids retention and usefulness. I am a nurse practitioner student and can also see the clinical connection. I have administered Methotrexate to many patients. Thank you.

Very high-yield. Thank you for underlining this moment, crucial in treating hypercholesterolemia.

I have taken biochem as an undergrad, grad. and post grad and I've never had anyone explain things as clearly. Dr. Ahern is one of the best teachers I've ever encountered. Thank you!

I am a student at Downey High and I really want to be a cardiothoracic surgeon, and I didn't know what to learn but I know this website will help me.

just basic to litle details course.easy to understand it.

A+ teaching style and delivery thank you Dr Ahern for making a difficult topic easier to digest

I think it is an entertaining way to learn the history of Biochemistry.

Actually I saw the YouTube add . And I watched the lecture . The information is given in short and precise manner. Understood everything.

The video helped me understanding this topic with visual representation

I love this guy. The way he explains makes Biochem look easier

A very well presented and in depth explanation of biochemistry. Dr Kevin Ahern also responds very quickly to questions. Definitely would recommend to anyone struggling with biochemistry like I was !

He is clear, short, and simplify the most important points

it is really amazing lecture & has been organized well thank you

I loved how I understood the bigger picture in the end of the lecture

Clear and Comprehensive explanation. Not too detailed but enough to understand.

he is very clear and is a nice teacher, and he use a appropiated nivel of technicims

I really liked this site ,and it's seems helpful for me . I am a high school student. I am in the 10th grade right now. I just want to become a surgeon doctor because I want to save peoples lives. I know that I have to right a commit to this site and I do not have to introduce myself for you people. I do not need to study this because I did not understand today's subject.I just want to be ready for the medical school. I hope this website will help me being ready and ,Good Luck.

I finally understood why we have Lineweaver Burk Plot and how we read it.

Very useful for people who don't know much! Concise, and well explained!

Was very clear just speak very quickly, then I have to repeat the lesson to understand complete anyway its not important, I would like just when speaking about the oncogenes give some examples about the food that causes

Very much explaining After I did this topics know is easy to undeerstanding

extremely helpful when the amino acids are divided in functional relevance.

Great lecture. You have a great and enthusiastic way of explaining.

Perfect way of explaining complex things. This is rarely seen by lecturers. Wow!

This lecture was explained super clear and to the point. Thank you!

Clearly explanations, every piece of knowledge that prof. Ahem shares with listeners is facilely absorbed and stays in the mind.

Attaractively and well explained video of serine protease catalytic mechanism that I have ever seen...Thank you..????

:) Thank you . everything in this lecture is clear. like it very much.

Very eloquent :) my favorite on this website! would definitely recommend.

thanks for your helpful for the all lovers of education

A good introduction. Very schematic and overall easy to learn basics.

This is only the first lecture and the first time I am delving into biochemistry for the first time, so hard to say, but something about Prof. Ahern's manner makes me curious and creates a fine feeling of anticipation. Great for a first lecture.

I was already following him before knowing lecturio. Nobody explains Biochemistry like him! Thumbs up!

it was described in a simple and easy way to understand, thank you.

This video did not really show Aspartic Acid or Glutamic Acid?

He very easily simplifies things. So this is why I give him a five star review

Amazing, loved it very much. Easy to follow and clear.

amazing ! thank you so much dear dr.Ahern , i was always scared of biochemistry ,but its the first time i finally get to understand it and i owe it all to you. My committee exam will be in two weeks and im hoping to finish this course plus few more lectures from fat metabolism course. also special thanks to lecturio for preparing such a great learning system opportunity for us.

concise and straight to the point,exactly what I was looking for

Amazing lectures! Very well explained and effective videos. A perfect way to get a clear view of the subjects, very glad I found this.

Awesome lecture, awesome proffesor. My teacher spent almost 1 hour explaining that. Thank you Dr. Ahern

Nice succinct intro with basic overview -- key points are highlighted

as a beginer i didnt couldn't understand anything the lecturer is talking about and the lecturer is way too fast

For the first time ever, I got AA right. Thank you!

I'll just say thank you very very very very much!!!

My name is Barbara, I'm from Colombia and I really like your videos Mr. Kevin, because I think the content is easy to understand.

informative course, to the point, easy to follow and understand, quiz questions are interesting

Vitamin section is fine, concerned vitamins explained clearly and easily However, some water soluble vitamins are considered missing (eg. thiamine, riboflavin, biotin, vitamin C ) although they might be encountered in some other subjects; such as nutrition. Additionally, minerals are not touched in these lecture series at all Overall, it is a very good course for the material targeted, but needs to fill the gap of missing items

Pure gold indeed !!! Presentation of chemical compounds during presentations is very helpful.

Love him so far, clear concise and to the point and also very enlightening

it is a very interesting materail, so clear an usefull and could recomend it without any question

Yea, these lessons site wide need more quiz questions. Only thing holding this site back from being outstanding.

Very well explained and detailed lecture, but it would be nice for better understanding to have some names and terms (e.g. Ramachandran plot) displayed in the video!

way too fast ????I really wish the teacher would talk slower as now I keep having to pause and rewind etc.

Direct , and easy to follow. The length of the video also helps.

Great professor but unfortunately the details of this lecture are not important for USMLE Step 1

Easy to understand and the explanation are very clear. Thank you very much good job!

well done, explained thoroughly, yet concise. Having a minimum word count on a review is a deterrent; please change this.

THANK YOU Pro Ahern you're amazing! very well explained!

Professor Ahern is a perfect teacher and he makes everything so easy to understand

Needs more details, and take it slower so that we the audience can get a more thorough understanding of the topic (the video really doesnt need to be that short)

I found it really helpful. Your explanations were clear and easy to understand.

Highly recommended lecturer for Biochemistry! I like his method, he is attractive teacher.

Thank you for the video's theses are really helpful. look forward to keep learning.

very nice clear and organized lecture. thank you. it adds alot to my simple knowledge

thanks for teaching me in such a clear, precise, and yet enriching way

Thanks for focusing on the "big picture!" The lecturer at my school bogged us down with the details, so it was hard to take in what the most important steps were

I Have watched only the free videos of basics of biochemistry as I seek to do Step 1 as an IMG. I like the smooth transitions and the questions at the end of each lecture. I seek to subscribe for the annual package soon.

excellent lecture. Cristal clear; not too slow not too fast, smooth transitions and a bright ending

prof Ahern is wonderful and funny! enjoyed all his lectures

It was very precise and up to the point. The presentation was interesting that triggers to study better .

very good lecture. pretty well organized and instructive. He has a deep knowledge of the material making me to pay special attention to all his lectures.

Very nice and informative lecture, easy to understand and remember

I have followed Dr Ahern through all the basics of biochem lectures and he has never failed to deliver.

Great job again Dr. Ahern! You have helped me better my understanding of these topics.

Great job, Dr. Ahern. Thank you for bettering my understanding of these concepts! Used as a supplement to lectures and powerpoints, your videos on Lecturio have been extremely helpful to me!

Very good lecture, l consider that is one of the most complete themes that l´ve read ...good job.

very informative and well explained lecture. Dr. Kevin Ahern has changed my view of biochemistry.

Brief, understandable, high yield information explained with illustrative slides by Dr. Ahern

Very well put. Dr Kevin Ahern explains difficult topics in a very short concise and interesting manner.

This guy deserves a medal. I wish I had a lecturer like this when I was in undergrad (or even now in medical school).

This entire series is the most eloquent and beautiful explanation of a terrible terrible subject like biochemistry I have ever seen to attended

Very helpful. Just passed final exam of Molecular biology and Biochemistry I-II with A+ Lectures are clear, made me understand the topics well sinceI had a good concept about the basics I could absorb more details and could recall immediately when needed. Highly recommended.

Hello Dr. Ahern. Your lectures were phenomenal, but for several of the lectures the slides did not correspond with your lecture (they were of totally different topics) or they changed midway into into unrelated biochemistry topics. It may be best to review them and adjust the errors. However, your presentation was so so good that I was easily able to follow your lectures with the downloaded lecture slides.

Its a little bit dificult to understand but the information its complete and tables and graphics helps a lot

Conveyed the process in a short &digestable way.I LIKED THE WAY OF presentation too.

Not bad, but need to identify the polymerases better, as in the replication of DNA and RNA...

Had so much difficulty learning the enzymes on the pathways. This way was easy to understand it!!

his teaching is clear and it is not allowing me to get even a single doubt

i could understand the concepts better. explanation was good.the charts were self explanatory. it made me feel bio chem much more interesting.

I like the way you link things from one to another. Yuu made these lectures highly appreciated with the concise and comprehensive explanation! Thanks Prof!

really helpful i never found this data in any of my textbooks

Not my favorite subject but very well explained and understanded.

Understood the lecture clearly. Very impressed by how clearly he explains things.

Wonderful! An awesome lecturer, he just has a unique way of passing the message. Great work Sir

He explains it very well and at a good speed. He doesn't use to many difficult words so if your first language isn't english it's still possible to understand. Also whenever you have a question he answers quickly en thouroughly.

It is really helpful. I appreciate your kind efforts. Thanks verh much.

i like your teaching .sir. it helps me to understand the concepts clearly.

Excellent information and explanation, it's helping me a lot. Congrats, lecturio!

Great lecturer very knowledgeable of subject matter at an admirable pace. Needed this in depth type of lecture in med sch. Good job

Great lecturer very knowledgeable of subject matter at an admirable pace. Needed this in depth type of lecture in med sch. This guy is just good.... Great job

Great lecturer very knowledgeable of subject matter at an admirable pace. Needed this in depth type of lecture in med school because signal transduction in med-school was highly schematic . Good job

Great lecturer very knowledgeable of subject matter at an admirable pace. Good job

Great lecturer very knowledgeable of subject matter at an admirable pace. I needed this in med sch. Good job

Great lecturer very knowledgeable of subject matter at an admirable pace. Good job

It was just amazing, he was critic to give information and had the most important skills for me, and that is: perfect didactic. Had all concise information I needed.

He simplified the concepts and illustrated by a very nice way

Excellent delivery of content which was easy to understand Good use of diagrams and graphs to help explain key concepts

This lecture helps me a lot since i jave a hard time to understand.

Prof Kevin Ahern makes even a complex signaling process easy to understand and the association with day to day events. I have loved his other lectures too. I literally used to hate biochemistry but now I’m enjoying it and that is why I have given his lectures 5 stars

very good outline and examples given in a step by step manner. Getting to like biochemisrty after years of putting this subject aside. Thank you.

It is very concise and practical it helps me a lot to understand in an easy way the collagen process.

High yield facts and clear explanation, the fundamental elements and efficient route to master biochem!

I am new to this curriculum, however, I would like the lectures to be longer. I am hopeful that other lectures are much more detailed, e.g. gene regulation/expression. Lecturer is very knowledgeable, clearly.

Thank you very much! Those extraordinarily awesome questions help me better understand the whole thing with details!

I liked very much this course. It's very interesting and The good teachers.

Wow, these two amines are very tricky, thank you very much, Prof. Ahern!

I liked the lecture and the diagrams, I can put 5 stars yet because I am unsure how relevant everything is. Pretty basic biochem, but it was a good refresher. The diagrams are helpful.

I cannot believe I am just now finding this resource during my dedicated Step 1 period. However, I am so glad that I found it now, right at the beginning of Step prep, rather than later. I plan to use this as one of my main resources for the remainder of time up until my exam. I realized while reading First Aid that, although I had known the subjects very well at one point, that my foundation was not as solid as it once was. This is perfect for reviewing and providing the big picture for everything. It's also an amazing resource for providing the "why" and "how" behind all the small factoids written in First Aid which is just what I need. It's so much easier to retain the information when you actually understand what is going on rather than memorizing a 650+ page book of bullet point lists/facts. This is great. I was a huge fan of Boards and Beyond, but I have since ditched that resource and am fully focusing on this one since this seems a lot more comprehensive and better taught (though Dr. Ryan has also done an amazing job too). Thank you guys so much for coming out with such a well thought out and developed and thorough resource. This is going to make board prep so much smoother. If I end up scoring highly on Step 1, I will make sure to write a review on Reddit, SDN, etc raving about Lecturio.

This guy is on top of his game at a ridiculous speed... I can't complain only if all others know their stuff like him there will be less confusion

The material covered a wide variety and having a non-science background it is clear and easy to understand.

This guy just knows his stuff, on point even with the speed of his speech he has mastered his slides. I almost got scared with the previous lecture in genetics but he managed to bring me back home. Very knowledgeable keep up the good work and add more clinical correlations.

Care for details and passion/curiosity for knowledge are seen in this lecture. I gained a lot from it.

I LIKE THE PRESENTATION AND I LEARN . PROFF. USE A SIMPLE AND UNDERSTANDABLE LANGUAGE

it's not helpful for the new medical student.lecture should be more prolong and specific,little slow mood.

Very profesional, why is it said that bacterial chromosome has a single origin of replication and eukaryotic multiple origins

Its really interesting subject made easy by an interesting professor. I'm not sure if that level of details are needed for the USMLE exam as I'm using the USMLE curriculum, if its not needed thats fine it will be for my future knowledge hopefully if i get to keep in my head.

It was simply amazing. The knowledge I got exposed to was simply clear cut and delivered by an expert in layman's literature. I am keen to absorb more of Mr. Kevin Ahern's lectures.

The lectures are nice, simple & very well explained. I would definitely recommend this course to my friends!

I like how Dr. Ahern took his time to explain the topic in an articulate manner. Helped me understand the topic and want to learn it more.

El semestre pasado apenas y me di cuenta de todo lo que la enzimas y las reacciones significaban, ahora creo tener una visión mucho ma completa, GRACIAS

Batalle mucho para entnder mis clases pero con estén curso tengo un mejor dominio de el metabolismo y me permitió realizar una presentacion del tema ????

Very easily to follow. The concepts are explained so that one who isn’t familiar with biochem can understand with ease.

Thank you so much Sir for brief description of all topics.

the lectures is shallow; i think that more details are needed. it is ineffectual for the level required from the biochemestry course of the Med University of Florence. cordially gioia

How I wish I had this when I first started medical school. The explanations were clear and concise. The use of simple words enable me to understand it well as well as the option to pause at anytime allows further internalization of the facts.

Recommend this course to any medical students doing pre/clinical Helps with pathways and understanding breakdown.

You can memorize or you can understand. Concepts are yours forever. Memorized lists of facts are gone the very next time you need to cram for another test.

Free trial makes lot of problems in watching the video .... Not properly organised app

Excellent! Well delivered and full of quality information. Totally recommend this course.

Dr. Ahern was very clear and concise. Great lecture. Thank you!

Doctor Ahren. Great explanations and enhances my knowledge in biochemistry, i´d rather reccomend you tu use a lower velocity on your explanations because some of the students are foreigners and they probably may lose the idea. Nevertheless i´m completely satisfied with your video lectures.

Simplified the lecture in enzymes and i like how everything was explained in a simple but direct way. :)

Amazing lecture and slides explained very well and it was useful to have the slides downloaded.

I finally understood why keto diet is so effective :) Thank you Dr. Kevin!

This lecture was very educational, and well organised, moving from the basics to the complicated topics, explaining every topic step by step.

Explains everything extremely clearly and made all of the processes easy to understand. This was a great lecture series!

Excellent lectures. The professor speaks very clearly. He makes it easy to understand.

Very good explanation of concepts. Animation could be added for excellent explanation.

The lecture was very intriguing! Dr. Ahern is so well articulated!

The Good: Lecture: 5/5 Amazing Lecture! I learned a lot! The Not so good: Quiz:2/5 Only 1 question....and was not as specific as I would like it to have been. Perhaps consider having at least 50% of the terms discussed included in the Quiz.

The best professor! He makes everything easier. Very good lectures.

The subject is really hard... but the professor is excellent!

Wow! Never thought I’d be amazed by the clarity and succintness of the discussion. Packs into a few minutes what would take a four hour lecture to discuss. Defintely recommended these lectures to my friends who are struggling with biochemistry and don’t want to use the books so much.

the lecture is good it educates on how bichemistry is related to other fields in life

thank you very much doctor kevinm very helpful lectures, especially vitamin D.

Thank you Dr Ahern! Thanks to your clear and nice explanations With integrations I am finally starting to understand Biochem! You make difficult things look so simple and enhances the importance and intelligence of mother nature in our human bodies

Incredibly good! I have spent hours studying from the book and this is by far the most helpful in terms of deep,meaningful understanding of the subject.

The courses are very concisely presented, it is really useful for preping for an exam

Need more details Need to go slower But overall not bad

It is very clearly and enthusiastically explained. You make Biochem easy to understand.

As a medical student I found this series of lectures on enzymes extremely clarifying. Dr Ahern is a great lecturer. Thank you so much.

The lecturer is very good at getting biochemistry across. Well explained and understandable up and until here.

Professor Dr. Kevin Ahern is very clear in presenting. Love the short but very informative lectures. Would recommend to everyone, those with or without biochemistry understanding. Thank you very much Professor and Thanks to the maker of Lecturio.

Kevin must be the best teacher ever. He explains with a certainty only a person with many years of lecturing can. Simple, easy and fast, making complicated matters seem easy to learn. Compared to the slides i have in med. school, the content is the same. But this guy also gives the explaination in the same amount of time! His body language is also nice to watch as they are firm and open, kind of directing your thoughts, like a maestro. You just have to remember and do some repetition of EVERY detail he mentiones, it will for sure be on the exam. I also use his lectures to simplify my understandings from pdf files from school and heavy textbooks. I will recommend everyone to use this!! Also i love the quiz afterwards. 1rst year university medicine

Fantastic lecture, just the amount of information I needed to cover and retain the topic.

Very clear summary. Would like to see more clinical correlations made.

Everything was on point .. Will definitely share with my friends.

I understood perfectly the concepts the way he explained them. He makes it ease to grasp

few things are missing like discoiling of histone protien and a sentence is not repeates

Very simple and easy to understand. Would definitely recommend this course.

Very concisely put, I love the lectures, very helpful indeed. Now all I need to do is work my ass off to get the dollars to pay for this awesome lecture. Thank you Lecturio!

I found the lectures to be very informative and composed of high-yield information for a relatively quick review of the subject. The only reason I give 4* is because of the few technical problems with the course; but, in regard to the course material, Lecturio provides a wonderful review of Biochemistry with Dr. Ahern.

It is really so good thing to take more information and I like so much the way of the explain for the teacher thank you so much for this helping for students

I love to use this great app to review my med knowledge!

I like the way that the AA are presented by a table between essentiel and non essential. I will use it for my memorizing process.

Great/clear explanation, definitely recommend to students. For those that complained, please describe what's needed to be explained, or just keep your pie hole closed. Being ambiguous is pointless.

no words can describe how much this was amazingly useful

I like the teaching style and material presented! It is clear and understandable. Thank you!

l am a pre-med student and after watching this lecture I decided I was definitely subscribing! Everything was explained clearly and I understood the concept completely.

Kevin Ahren explained the part very well. I liked the way he explaining this part. I am from business back ground.

Brief and comprehensive lectures. Really makes mechanisms and actors really to understand.

Both comprehensive and simple lectures, could use some more medical/clinical correlations, though.

i like this lecture. way of representing and explaining is quiet good.

It is fantastic to have a lecturer making a diffucult subject easy. Now i can not wait diving into some hardcore books about enzymes. Watching an inspiring teacher really makes a difference. This guy is also rather fast talking so you dont need to speed up, witch i do quite often. Also the pop quiz in the end just makes it so much more fun. It becomes a game. And thats great and enhances long term memory.

Very nice but there's some need of detailed explanation and then it would be perfect

Thank you so much Dr Kevin, this lecture series are the best that I have seen so far and explain very well, simple and practical a very complicated topic.

he is so good ... I am very thankful to you sir !!

it was perfect and describe a part of endocrine system very well.

A great, insightful lecturer. A Prof. at the top of his game. Miss his long hair though (checkout his youtube site)!

Easy to understand with the structure of the molecule. Very clear and straight forward.

Great Instructor. Clear, concise, very easy to comprehend. Dr. Ahern gives the "meat" of the concept. Not long winded.

Awesome job, I wish you were my teacher at my university! So clear!

I subscribe because of this professor. Great lectures and explanation. Nice job

It had been a few years since reviewing enzyme kinematics, this was a great refresher!

thank you very much, nice lecture, sounds great, well presented

It was very clear and explained well- the subject itself is usually hard to explain

it´s great conference, well explain, clear and simple. like ir a lot

very good course, i wish i have money to pay the all course

The facilitators are very good because they motivate you to learn.

thanks. the lecture was very informative and concise for such a complicated topic

excellent work by professor to make biochemistry understandable for all

Thanks Dr. Kevin Ahern. Believe me when I say that I have a teacher who just read his lectures. I think that Biochemistry is a hard subject and difficult to understand because most of the things are just known perfectly reactions and structures. But your lectures have something else. I take some notes and it's easier for me to study the subject. Before I started with Lecturio most of my subjects I didn't know how to study. There is only one thing that I would like to suggest. I would like to know some facilities that teachers and students use for know the structures.

the plot charts are really confusing. takes a few replays to grasp a little.

Lecturer seems to know the material and is able to convey in a manner that is engaging

These lectures are made simple for someone like me who is very vulnerable to biochemistry.

Thank you Dr. Kevin Ahern!!! Sometimes you speak so fast, but these time was perfect :)

The professor was very clear and his tone was lively :)

Dr. Ahern is a fabulous instructor. He goes into just enough detail on all the important content and pathways, bringing everything into a more holistic view of biochemistry. A+!!!!

As it's my first lecture, I think I have to work a lot for getting great benefits from your great tutors. hence I had to give this rate. right now there are no such dislikes. well, thanks a lot for the kind assistance.

These lessons are brilliant enjoyed them so much I have bought some books by Kevin Ahern, PhD the questions at the end also reinforce learning.

I was impressed by the knowledge of the professor. However, the very short length of each lecture was disturbing and distracting.

Great lecturers and thorough explanations for every subject. After watching the lectures, I actually understood and retained because his lectures are extremely well organized.

this guy so good only amazing so much only omg nice nice

This is quite helpful. I am a pre-Medical student and I'm fully satisfied by the leacture. I'm able to cover all the syllabus. It's helping me to save time. I dont need all those notes n stuffs. Most important i can practise lots of questions! I'll recommend all Medical students to take this amazing leacture for once so that you'll be able to understand. Thankyou @lecturio! ????

Great professor, great explanations. This video was like a summary of important parts.

it was very good lecture it will help me in my med biochem class thanku

A ERY INTERESTING COURSE ,BUT REQIURES A LLOT OF STUDY TIME TO UNDERSTAND THE AMINO ACID CHEMISTRY. TO BE HONEST, I AM A RETIRED 85 YR OLD PHARMACIST TREYING TOEEP UP.

I really like the pace and clarity of this lecturer in how he presents the material. It would be nice to have animated pictures in signaling and transport. I also wish there were sections covering enzymatic catalysis & kinetics. Over all, very good! Thank you for making these

Exactly what I needed. Straightforward and to the point. Linearly organized.

Very helpful Keep it up .. easy to understand . Lecture in a simple way

Hello though I learnt new things by the good explanation of the pathway but I will be happy if there could be mnemonics to remember then easily. Thanks

I rate this five stars because I like to go over it while I do other things and more than once.

The overview of biochemistry is really helpful! The images are great, and the lecture is really high quality.

it is a good course. easy to understand. I liked this course

I was hoping for a little more details about the chemical makeup of the topic, however, I like how the entire video is layed out and described.

this Professor is really an encouraging one, he knows how to contact with his students, he has a deep knowledge, it is my first time to encounter this type of unbelievable professor.. more power Professor Kevin Ahern, from Philippines Honeylette Tayong :) thank you so much sir I really learned a lot from you, and aside from that you really motivated me to study deeper than I can ;)

This is professor is really good at explaining concepts and is thorough with getting caught up in the details

Seriously gifted biochem lecturer. One of the best on here in my opinion. He explains everything so clearly. Lectures are organized and images are really helpful!

Thank you very much for such a great lectures!Biochemistry have never been so interestig until now)

A very clear understanding of the basic concepts was developed by Kevin. Good examples and perfect illustrations made everything so easy and interesting.

Watching these videos from Lecturio is very much like being in my school. The difference is Lecturio is more fun and it encourages us every time we want.

very clear Explanation; I managed to understand mechanism for each type of Ihnibitors thus I can now draw the lineweaver plots.

Great constructive instruction at a understandable medical level thank you! Thelma Boshoff

With this introductory course, you will be exposed to the basic aspects of Biochemistry. Professor Ahern emphasizes that an in-depth knowledge of basic biochemistry will aid you tremendously in understanding life processes on a macroscopic level. This one course alone was well worth the one month payment of 24$. Every other course on top of that was an attractive but inessential addition..."icing on the cake"!

Excellent course! Whether you want to review biochemistry for a Board/National exam, or you are looking for help with a Biochemistry course. Professor Ahern details the fundamental aspects of biochemistry in a way that will make the importance of the many unseen molecules and processes stand out in all of their relevant glory!

The professor has a very clear explanation and teaches in a really dynamic way. The only negative thing about the course is that it's missing some essential biochemistry topics for graduation level like the citric acid cycle

It's the best. I really love how the doctor explains the concepts with simplicity. Biochemistry became much easier to understand. If it included clinical cases it would have been better.

Professor Ahern is truly excellent! Amazing choice. He clearly explains concepts and shows sincere enthusiasm for the topics. You need to bring him back for lectures on amino acids and the urea cycle as well as the electron transport chain.

The explanation given by Sir is very easy to understand and I able to remember for a long time.

Very easy to follow, good flow and simply explained, exceptional professor! just wish the questions had explanations then I would give the videos a higher score .

I like this course ,well explained it does cover a lot . It really helped me to get a good mark and information

it has helped me build my understanding of biochemistry. looking forward to more lectures

Love this course and Professor Ahern's enthusiasm keeps my attention. Being able to watch the videos over and over helps the lessons sink in. For the first time I'm enjoying biochemistry. Thank you for making these videos so affordable and easy to use.

Starting Biochemistry in the Fall and a little nervous..so I decided to brush up with self-paced lectures on Lecturio. Prof Ahern is amazing! His lectures make it easy to remember and the quizzes in each module force me to look up answers. So this is fantastic for those whose like to teach themselves. I also downloaded Biochemistry free and Easy and it complements the course nicely.

Since is starting this biochemistry, it's help me to remember some of the basic concepts that I have forgotten

I'm starting medical school on August 7th. I'm anticipating some material I'll be trained on in advance.

This is an amazing course! Prof Kevin has made every single details simple and clear. His deep knowledge and understanding of this subject is well reflected in his teaching style. The materials he used, are very attractive which makes it easy to memorize. I would definetly recommend this for both under and postgradustes students.

This course is well done. It's thorough. I'm reviewing things I've learned, and also moving on to more advanced material very soon. I wish I would have had this during undergrad.

Lectures themselves are very good and very comprehensive and detailed. It would be useful to know how much of the specifics of biochemistry are likely to be examined in board exams...I was under the impression board exams are leaning towards understanding concepts rather than specifics such as the mathematics/calculation of enzymes activity.

The biochemiThe biochemistry is one of the best because the professor Ahern is a terrific docent who makes one love the lectures
