Its free cysteine thiol makes it the dominant low-molecular-weight antioxidant in most cells, participating in redox buffering, detoxification, and disulfide exchange. In the laboratory it is a standard reagent for reductive cleavage of disulfide bonds, for measuring oxidative stress (via the GSH/GSSG ratio), and for studying glutathione peroxidases and S-transferases. Research applications Reference antioxidant for redox-balance / GSH:GSSG assays Reagent for reductive cleavage of disulfide bonds Substrate/cofactor in glutathione-enzyme research Quality & documentation Every lot is tested by an independent third-party laboratory before it enters the catalog.
