Glutathione is a tripeptide (?-L-glutamyl-L-cysteinyl-glycine) with characteristic gamma peptide linkage, available as a lyophilized powder for laboratory research.
Glutathione (GSH) is a tripeptide: L-glutamic acid, L-cysteine, glycine. Features gamma peptide linkage between glutamate side chain carboxyl and cysteine amino group (not typical alpha bond).
Contains free thiol (-SH) on cysteine central to redox chemistry. Exists as reduced (GSH) and oxidized (GSSG, disulfide dimer) forms. GSH:GSSG ratio indicates cellular redox state. Provided as reduced form. Store at -20°C protected from light, oxygen, moisture; use promptly after reconstitution.
