Glutathione is a tripeptide formed by a peptide linkage between the amine group of cysteine linked to glycine and the carboxyl group of the glutamate side-chain. It is an abundant cellular reducing agent, whose major biological function is mitigating oxidative damage to biological macromolecules.
Glutathione exists in both reduced (GSH) and oxidized (GSSG) states. In the reduced state, the thiol group of cysteine is able to donate a reducing equivalent (H++ eâ) to other molecules, such as reactive oxygen species to neutralize them, or to protein cysteines to maintain their reduced forms.
