WebbThe pentose phosphate pathway is a metabolic pathway parallel to glycolysis to form ribose-5-phosphate, which can be used to synthesize nucleotides. The net equation of the pentose phosphate pathway is: Glucose 6-Phosphate + 2 NADP + + H 2 O ↔ Ribose 5-Phosphate + 2 NADPH + CO 2 + 2H +. WebbThe 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. http://www.columbia.edu/cu/biology/courses/w3034/Larry/readings/PurineChapter/PurineChapter.html customized database software
