L-Glutathione Reduced is an endogenous antioxidant, with the ability to scavenge oxygen-derived free radicals. L-Glutathione Reduced is a non-protein thiol widely present in living cells, which plays an important role in a series of biological events, including protein and DNA synthesis, enzyme activity, metabolism as well as cell protection. Not only does L-Glutathione Reduced scavenge oxygen-derived free radicals which contribute to the development of many common diseases including cancer, heart attack, stroke, arthritis, but it also helps in regenerating other antioxidants such as vitamin E and ascorbic acid. Thus, L-Glutathione Reduced is established to be a marker of oxidative stress. In addition, L-Glutathione Reduced is used for eluting glutathione S-transferase (GST) from glutathione agarose.?
