Glutathione (GSH) is named Reduced glutathione or L-Glutathione Reduced , an essential antioxidant in plants, animals, fungi, and some bacteria and archaea, a white crystalline powder. It is a tripeptide with a gamma peptide linkage between the carboxyl group of the glutamate side chain and the amine group of cysteine. A standard peptide linkage attaches the carboxyl group of cysteine to a glycine. Thiol groups are reducing agents, existing at a concentration of around 5 mM in animal cells. Glutathione reduces disulfide bonds formed within cytoplasmic proteins to cysteines by serving as an electron donor. In the process, glutathione is converted to its oxidized form, glutathione disulfide (GSSG), also called L-glutathione.
