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). Web6.1.4 Glutathione reductase (GR) Glutathione reductase (GR) is a part of antioxidant defense systems of plants and microbes, and it also takes part in both enzymatic and nonenzymatic oxidation reduction processes of the cell.
