Glutathione
Reduced tripeptide. Loti Labs supplies it as lyophilized powder in 600 mg and 1500 mg vials, for laboratory research.
HOOC-CH(NH2)-CH2-CH2-C(=O)NH-CH(CH2-SH)-C(=O)NH-CH2-COOHγ-ECG = γ-L-glutamyl-L-cysteinylglycine. The first bond joins the glutamate side-chain γ-carboxyl carbonyl to the cysteine amino group, not the glutamate α-carboxyl group. Glutamate retains its free α-amino and α-carboxyl groups. Cysteine carries a free thiol (-SH); glycine has a free C-terminal carboxyl group. This schematic shows connectivity, not stereochemical bond geometry.
