WebAug 7, 2024 · The pentose phosphate pathway (also known as the hexose monophosphate shunt, HMP shunt) consists of both oxidative and nonoxidative components (Fig. 27.1). In the oxidative pathway, glucose 6-phosphate is oxidized to ribulose 5-phosphate (ribulose 5-P), CO 2, and NADPH. 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.
