WebThe major source of NADPH in animals and other non-photosynthetic organisms is the pentose phosphate pathway, by glucose-6-phosphate dehydrogenase (G6PDH) in the first step. The pentose phosphate pathway also produces pentose, another important part of NAD (P)H, from glucose. Web1. dec 2024 · The reactions of the pentose phosphate pathway. The pentose phosphate pathway is classically divided into the oxidative and non-oxidative arms. The oxidative arm functions to provide NADPH required for cellular biosynthesis and redox balance. The non-oxidative arm provides precursors for amino acids, nucleotide and co-factor synthesis.
