The products of the transketolase reaction for given substrates. Concept introduction: The alternative pathway of glucose oxidation is pentose phosphate pathway, which includes 2 phases namely oxidative phase and non-oxidative phase. The principal products of the pentose phosphate pathway are the ribose-5-phosphate and NADPH. At stage 3 of pentose phosphate pathway, carbon–carbon bond cleavage and formation occur and is catalyzed by transaldolase and transketolase.
