About Glutathione
Glutathione is a tripeptide of glutamate, cysteine and glycine (gamma-L-glutamyl-L-cysteinylglycine). Its distinguishing feature is a gamma peptide bond between the side-chain carboxyl of glutamate and the amino group of cysteine. The free thiol group on the cysteine residue is what makes the reduced form, GSH, chemically reactive.
It is supplied as a lyophilized powder in 500 mg, 1000 mg and 1500 mg vials. Store it lyophilized at -20°C, protected from light. Keeping it cold and dry limits oxidation of the thiol group. A certificate of analysis is posted for each size as its lot is tested, and the size table on this page shows which sizes have one. It is sold for laboratory research use only and is not for human or veterinary use.
