After glucose enters cells, it can be converted into pyruvate and lactate through glycolysis, or it can enter the pentose phosphate pathway to generate NADPH and ribose phosphate. HK, PGI, PFK, and G6PDH correspond respectively to glucose phosphorylation after uptake, G6P/F6P interconversion, ...
Glucose-6-phosphate dehydrogenase (G6PD) is the key rate-limiting enzyme of the oxidative phase of the pentose phosphate pathway (PPP). It catalyzes the oxidation of glucose-6-phosphate (G6P) to 6-phosphoglucono-δ-lactone while reducing NADP⁺ to NADPH. NADPH is pivotal for antioxidant defense, ...
Glucose metabolism is a core network for cellular energy conversion and carbon allocation, spanning glycolysis, gluconeogenesis, glycogen synthesis and breakdown, the pentose phosphate pathway, and the tricarboxylic acid (TCA) cycle.
