WebThe pentose phosphate pathway occurs in the cytosol consists of two distinct phases, the oxidative and non-oxidative. As for the former, the primary result is the conversion of glucose-6-phosphate (G6P) into ribulose-5-phosphate and CO2 and the generation of reduced NADPH. WebThe pentose phosphate pathway (PPP) is a fundamental component of cellular metabolism. The PPP is important to maintain carbon homoeostasis, to provide precursors for nucleotide and amino acid biosynthesis, to provide reducing molecules for anabolism, and to defeat oxidative stress.
