02Mechanism of Action
Glutathione (GSH) is an endogenous tripeptide (γ-glutamyl-cysteinyl-glycine) and the cell's principal thiol antioxidant. Its reactive cysteine thiol neutralizes reactive oxygen species and serves as a substrate for glutathione peroxidase in redox-balance research.
It also participates in phase-II detoxification via glutathione-S-transferase conjugation, making it a core tool in oxidative-stress and detoxification studies.

05FAQ
What is glutathione used for in research?
Glutathione is the endogenous tripeptide master antioxidant studied for redox balance, ROS scavenging, and phase-II detoxification in research models. It is sold for research use only.
What is the structure of glutathione?
Glutathione is a tripeptide with the sequence γ-Glu-Cys-Gly, molecular weight approximately 307.32 g/mol, and CAS number 70-18-8.
Why is the cysteine residue important?
The cysteine thiol (-SH) group is the reactive center responsible for glutathione's antioxidant and conjugation chemistry studied in redox research.
How should Glutathione be stored?
Glutathione ships lyophilized and should be handled per standard research-peptide practice — kept cold, protected from light and moisture, and reconstituted only for laboratory use. Cold-chain handling is used where required. For research use only.
Is Glutathione approved for human use?
No. Glutathione is sold strictly for laboratory research use only and is not a drug or supplement. It is not approved for human or veterinary use or consumption.
How is Glutathione tested at Ethos Bio?
Every Glutathione lot is independently verified by MZ Biolabs, a third-party analytical laboratory in Arizona, on a five-point panel — RP-HPLC purity, HPLC-MS identity, endotoxin (LAL), heavy metals, and sterility. A lot-specific certificate of analysis ships with the vial. See How We Test for the full methodology.
