Glutathione Peptide: What It Is and Research Applications
Glutathione is a tripeptide and one of the most abundant antioxidants in biological systems. It is widely studied in laboratory research for its role in cellular redox homeostasis.
Chemical properties
- Sequence: gamma-Glu-Cys-Gly
- Molecular formula: C10H17N3O6S
- Molecular weight: ~307.3 g/mol
- Appearance: White to off-white lyophilized powder
Research applications
Glutathione is studied for its role in:
- Redox signaling — the GSH/GSSG ratio is a key marker of oxidative stress
- Detoxification — conjugation with xenobiotics via glutathione S-transferases
- Immune function — lymphocyte proliferation and signaling
- Mitochondrial function — protection against oxidative damage
