WebGlutathione (GSH or reduced glutathione) is a tripeptide of gamma-Glutamyl-cysteinylglycine and the predominant intracellular antioxidant in many organisms including humans. GSH and associated enzymes are controlled by a transcription factor-nuclear factor-2 related erythroid factor-2 (Nrf2). WebGSH is a naturally occurring antioxidant in grapes and is found in especially high concentrations in Sauvignon Blanc. In wine, it can react with quinones, which can oxidize the volatile thiols, thereby depressing their aromatic impact. GSH can also preserve esters, terpenes and wine color during aging, according to multiple studies.
