Purine and Pyrimidine Metabolism

by Kevin Ahern, PhD

Purines (adenine and guanine) and pyrimidines (cytosine, uracil, and thymine) are key components of nucleic acids, the building blocks of DNA and RNA. These compounds need to be synthesized within cells before they can be incorporated into the longer polymers.

In this course, the student will be introduced to the metabolic pathways of purines and pyrimidines, with discussions about synthesis and catabolism.

For optimal comprehension, the student will be required to be familiar with the basic notions of molecular and cellular biology and the biochemistry of nucleic acids.

Good and clear lectures! Thank you
By Ana Z. on 29. November 2021 for Pyrimidine Catabolism and Salvage Reactions

All of the videos on this topic are very good, thank you!! It made me finally understand it. I wish we would have more details on the pathologies related to the Purine and Pyrimidine pathways.

Hard to understand
By Daniel D. on 18. March 2021 for Purine and Pyrimidine Metabolism

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

By KARMELIA S. on 06. September 2020 for Pyrimidine de novo Metabolism: OMP Decarboxylase and Synthesis of UTP & CTP

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

Exellent resource for medical students.
By King D. on 02. September 2020 for Paths to Guanine and Adenine Nucleotides

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