Brief summary: PPP drives the formation of reducing agent, NADPH (used in fatty acid synthesis), and pentose sugars which are used for glycolysis and nucleic acid synthesis. Glucose-6-phosphate, catalysed by enzyme glucose-6-phosphate dehydrogenase, reduces NADP+ into NADPH. The final net result of this oxidative branch pathway is ribulose-5-phosphate and 2 NADPH molecules. Ribulose-5-phosphate can get converted into xylulose-5-phosphate which is further converted into fructose-6-phosphate. Fructose-6-phosphate is utilised in glycolysis where glucose is broken down into pyruvate to generate ATP. Ribose-5-phosphate is also used for the production of PRPP which determines pyramidine and purine nucleotide synthesis. This process mainly occurs in the liver and adipose tissues where NADPH can be utilised to donate electrons required for fatty acid synthesis. PPP is regulated by the activity of glucose-6-phosphate dehydrogenase where NADPH can allosterically inhibit its activity at high concentrations.

I think it would be much easier to follow along if you also presented the chemical structures of the starting materials, intermediates and products. I think this would help with understanding, vs just cramming. Thank you for your videos.

I have Mediterranean variant; I have almost no g6pd. Every time I have surgery, I go into hemolytic anemia. It is X recessive, but due to lyonization, someone like I, can be very fragile and react with the slightest oxidative stressor. I was just in the hospital requiring transfusions because I pet a dog that had just gotten the flea and tick ointment administered on their neck.

Thank you JJ for all your amazing videos!! It would be great if you could do a lesson on the areas of the brain that lack a blood-brain barrier (I think circumventricular organs.. hypothalamus, etc.). A lot of people I ask at my university do not know much about the areas of the brain that lack a BBB and their physiological functions. I would love to learn more myself on this topic and it would be much appreciated if you were able to make a video. Thank you either way!
@lindav11892 жыл бұрын
Babies with high and prolonged jaundice do not have the BBB and within the first week of their lives, they can go from being born perfectly healthy to severely brain damaged. Kernicterus, sadly destroys a child. The mothers of these children say they can't even look at their baby's first days, and most have PTSD from the disaster. Women go home and THEN the jaundice hits, some doctors even downplay it. This is not part of newborn testing in most of United States.
