Research brief · Longevity
Glutathione
Tripeptide master antioxidant used in redox and detoxification research.
Class
Tripeptide antioxidant (Glu-Cys-Gly)
Half-life
~10 min (plasma)
Studied in
Oxidative stress, detoxification and cellular redox research.
What it is
Glutathione is the principal intracellular thiol antioxidant, a Glu-Cys-Gly tripeptide central to cellular redox homeostasis, GPx-mediated peroxide reduction and phase-II detoxification.
Mechanism studied
Primary intracellular thiol antioxidant; cofactor for GPx, GST enzyme families.
Research notes
- Studied across hepatic, neuronal and dermal redox models.
Before sourcing any material
- Confirm a lot-matched third-party certificate of analysis (HPLC purity and mass-spectrometry identity).
- Check the stated peptide content per vial, not just the gross vial mass.
- Plan reconstitution volumes first so the vial size matches your protocol.
- Verify what is lawful in your jurisdiction — these are in-vitro research reagents, not medicines.
