Witryna16 kwi 2024 · GPX and GR are two key enzymes involved in the glutathione (GSH) redox cycle, where GPX uses GSH to reduce organic peroxide and H 2 O 2, and GR reduces glutathione disulfide (GSSG) to GSH in a nicotinamide adenine dinucleotide phosphate (NADPH)-dependent manner .

WitrynaGlutathione reductase is one of a chain of enzymes which serves to maintain glutathione in the reduced form. In vitro, this enzyme can function with either NADH or NADPH as hydrogen donor ( Francoeur and Denstedt, 1954; Kaplan and Beutler, 1968 ). In vivo, however, only NADPH is effective ( Beutler and Yeh, 1963; Rieber et al., 1968 ).
