GSHglutathiondisulfid
GSHglutathiondisulfid, also known as glutathione disulfide (GSSG), is the oxidized form of glutathione (GSH). Glutathione is a tripeptide composed of glutamate, cysteine, and glycine, and it is a crucial endogenous antioxidant and detoxifying agent found in virtually all living cells. In its reduced form (GSH), it plays a vital role in protecting cells from oxidative damage by scavenging reactive oxygen species and detoxifying xenobiotics.
GSSG is formed when two molecules of GSH lose two hydrogen atoms and a disulfide bond is
The regeneration of GSH from GSSG is a vital cellular process facilitated by the enzyme glutathione reductase.
