WitrynaThe remaining amount of glucose is metabolized through the pentose phosphate pathway whose main function is the production of redox potential in the form of NADPH. NADPH acts as a cofactor of glutathione reductase, which maintains glutathione in its reduced state (GSH), thereby providing protection against oxidative stress 6. WitrynaThe pentose phosphate pathway (PPP) branches from glucose 6-phosphate (G6P), produces NADPH and ribose 5-phosphate (R5P), and shunts carbons back to the glycolytic or gluconeogenic pathway.
