Pentose phosphate pathway nucleotides
WebThe pentose phosphate pathway (PPP) is a metabolic pathway that runs parallel to glycolysis. It is a crucial source for NADPH generation for reductive biosynthesis [3] (e.g. fatty acid synthesis) and pentose sugars.

WebThe pentose phosphate pathway (PPP) is a metabolic pathway that runs parallel to glycolysis. It is a crucial source for NADPH generation for reductive biosynthesis (e.g. … WebThe primary functions of this pathway are: 1. To generate reducing equivalents, in the form of NADPH, for reductive biosynthesis reactions within cells. 2. To provide the cell with ribose-5-phosphate (R5P) for the synthesis of the nucleotides and nucleic acids. 3. Although not a significant function of the PPP, it can operate to metabolize dietary pentose sugars …
