Antioxidant
An antioxidant tripeptide investigated in cellular research.
Type
Tripeptide (gamma-glutamyl thiol)
Molecular formula
C10H17N3O6S
Molecular weight
307.32 g/mol
CAS number
70-18-8
Amino acids
3
Sequence
gamma-Glu-Cys-Gly
Modification
Gamma-glutamyl isopeptide bond; free cysteine thiol (reduced form, GSH).
A gamma-glutamyl tripeptide bearing a reactive cysteine thiol; it serves as a co-substrate for glutathione S-transferases and an electron donor for glutathione peroxidases, cycling between reduced (GSH) and oxidized (GSSG) states.
Research Focus
Studied in redox-biology, oxidative-stress and detoxification-enzymology research.
Lyophilized
-20°C
store desiccated; air-sensitive.
Reconstituted
-20°C
prepare fresh; the free thiol oxidizes readily in air.
Air-sensitive (thiol oxidation to GSSG); store under desiccant; avoid prolonged solution storage.
Also known as: GSH, L-glutathione (reduced)
