Glutathione 600mg (GSH) is the reduced form of the tripeptide L-γ-glutamyl-L-cysteinylglycine, supplied as a high-purity lyophilized powder for laboratory in-vitro research use only. As the predominant low-molecular-weight thiol in living cells, reduced glutathione serves as a foundational reference compound in redox biology, allowing researchers to probe how the cysteine sulfhydryl group participates in electron donation, thiol-disulfide exchange, and the maintenance of intracellular reducing conditions.
Mechanistically, GSH functions as the substrate through which glutathione peroxidases neutralize peroxides and glutathione S-transferases conjugate electrophilic species, cycling between its reduced (GSH) and oxidized (GSSG) states. In cell-culture and preclinical model systems, investigators use it as a defined tool to characterize antioxidant defense, the GSH/GSSG ratio, and downstream detoxification chemistry.
Key research areas
- Cellular redox balance and oxidative stress models, including GSH/GSSG ratio measurement
- Detoxification pathways and Phase II conjugation chemistry via glutathione S-transferases
- Mitochondrial function and protection studies in cultured cells
- Antioxidant defense mechanisms and thiol-dependent enzyme activity
- Reference-standard applications for peroxide-scavenging and free-radical assays
