Glutathione exists in reduced (GSH) and oxidized (GSSG) states. The ratio of reduced glutathione to oxidized glutathione within cells is a measure of cellular oxidative stress where increased GSSG-to-GSH ratio is indicative of greater oxidative stress. In healthy cells and tissue, more than 90% of the total glutathione pool is in the reduced form (GSH), with the remainder in the disulfide form (GSSG).

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 ).
