WebApr 21, 2024 · Pentose phosphate pathway (PPP) is one of three key central metabolic pathways. It is ubiquitous, present in both prokaryotes and eukaryotes, and occurs in cytosol. It is a major source of the reductant, NADPH and pentose sugars for the biosynthesis of nucleotides. Also, PPP is the main pathway for pentose utilization.
WebPentose phosphate pathway [ edit] When the ratio of NADP + to NADPH increases, the body needs to produce more NADPH (a reducing agent for several reactions like fatty acid synthesis and glutathione reduction in erythrocytes ). [1] This will cause the G6P to be dehydrogenated to 6-phosphogluconate by glucose 6-phosphate dehydrogenase.
