    Ninja Nerds!
    In this lecture Professor Zach Murphy will present on the pentose phosphate pathway. We discuss how glucose can use an alternative pathway to make NADPH's, which are essential in antioxidant reactions, cholesterol synthesis, and fatty acid synthesis. It's also important in the synthesis of nucleotides. We hope you enjoy this lecture and be sure to support us below!

      It was barely mentioned at our medschool university (just randomly inbetween something else) and then it popped up multiple times on the exam where we were just supposed to memorize a random enzyme at a certain step etc. It is fair to say that the majority is up for credit test as the first midterm was just as bad. I wish they tested us in understanding rather than pointless memorization.

    A little note to take at 17:17 very important correction...
    it's unfortunate we can not draw diagrams in the comment section but I hope this piece helps out .. 😆😂😂
    Ribulose 5-phosphate is first epimerized to xylulose 5-phosphate. Transketolase catalyzes the transfer of a two-carbon fragment from a ketose donor to an aldose acceptor .In its first appearance in the pentose phosphate pathway, transketolase transfers C-1 and C-2 of xylulose 5-phosphate to ribose 5-phosphate, forming the seven-carbon product sedoheptulose 7-phosphate . The remaining three-carbon fragment from xylulose is glyceraldehyde 3-phosphate.

  • @GodfreyMann

    24:52 is where he explains the point of this pathway.
    Basically, there are two phases:
    (a) Oxidative Phase that can generate NADPH and Ribose-5-P.
    (b) Non-Oxidative Phase that makes Ribose-5-P without NADPH using glycolytic intermediates, and in reverse it can make glycolytic intermediates from Ribose-5-P.
    Note: Glyceraldehyde-3-P (GA3) in steps (5) & (7) can be funnelled into glycolysis or gluconeogenesis.

    Great stuff!
    I am going thru ur biochem videos just for fun. I remember, as a student long ago, loving the maze of the various metabolic pathways. For each pathway, there three points that must be made and emphasized.
    1. The key, rate-limiting enzymes/reactions.
    2. The main purpose or role of the pathway. What primary purpose does it serve?
    3. The net energy balance (yield or cost)
    You described the pathway and what it is good for beautifully.

    Love your videos, very informative! Theres a slight error i feel you made though; its the xylulose -5-phosphate that donates the two carbons NOT the ribose-5-phosphate. The xylulose-5-phosphate is the donor ketose and the ribose-5-phosphate is the acceptor aldose which becomes glyceraldehyde-3-phosphate.
