The tripeptide gamma-Glu-Cys-Gly, the most abundant low-molecular-weight thiol in cells. Used as the reference standard in GSH/GSSG redox measurements and as the substrate in glutathione S-transferase and glutathione peroxidase assays. The free thiol oxidizes to the disulfide GSSG readily, which is why it is stored cold and desiccated.

The thiol tripeptide, gamma-Glu-Cys-Gly: the first bond runs through the glutamate side chain rather than its alpha carboxyl, which the plain sequence above does not show. Cheapest line in the catalog and the one most sensitive to oxidation.
