Biochemistry is the branch of science concerned with studying the chemical processes and substances that occur within living organisms.

Biochemistry and medicine enjoy a mutually cooperative relationship. The many functions that human organs perform are oftentimes based on chemical processes. One cannot hope to master the comprehension of Physiology without a solid grasp of Biochemistry, the basis of all metabolic processes.

The substances and reactions that are the subjects of the study of Biochemistry are also important players in the understanding of cellular biology, microbiology or the effects organisms can have on the human body, and the pharmacologic effects of medications.

My rating of Carbohydrate metabolism

I have really learned. Before, I was wondering why study, or cram all those pathways and enzymes. How Professor Kevin Ahern explains and bring out concepts, Oh my God so great. He was born a teacher and just polished by learning! He never leaves behind any one, even the slow learners can pick, because once one understands the basic, the necessary complex facts can be understood quite faster! I am now thinking of mastering in Biochemistry, besides my goal of Internal medicine. To be the best Physician, Biochemistry I have understood is one of the vital tools! In my Nursing practice, we lost a 10 yr old male with Liver Cirrhosis from a liver disease, which was diagnosed in early age. Now, I am thinking of a Deficiency of the Transaldolase enzyme!! Ahh save for my little knowledge! Kind regards!

Thank you

Really a great and elaborate presentation. Thanks Prof. Kevin. Now I no longer struggle in cramming Biochemistry but rather find the subject interesting. I wish I started using your lecture guide early in Medical school, but any way not yet late! Thank you once again.
