Product Specifications
Descriere
Toate informațiile prezentate se bazează pe publicații științifice, care pot fi consultate la sfârșitul descrierii produsului, mai jos.
Glutathione (GSH) is a tripeptide composed of glutamate, cysteine, and glycine — the primary intracellular antioxidant defense system in mammalian cells.
Research Highlights
1. Antioxidant Defense — Most abundant non-protein thiol in cells. Neutralizes ROS and regenerates vitamins C and E.
2. Detoxification — Major phase II mechanism via glutathione S-transferases. Critical for hepatic drug metabolism.
3. Immune Function — T-cell activity and NK cell function depend on adequate intracellular GSH concentrations.
4. Mitochondrial Protection — Essential for membrane integrity and electron transport chain function.
5. Skin Health — Investigated for melanin synthesis inhibition and UV protection.

Întrebări frecvente
- Glutathione (GSH) is a tripeptide with structure γ-L-Glutamyl-L-cysteinyl-glycine (γ-Glu-Cys-Gly). Molecular formula C₁₀H₁₇N₃O₆S, molecular weight ≈ 307.3 g/mol. The unusual γ-glutamyl bond makes it resistant to most peptidases.
- Each batch is HPLC-verified at ≥99% purity, with the cysteine thiol group quantified to ensure the reduced form (GSH) is supplied. COA included.
- Store lyophilised GSH at -20 °C, sealed and protected from light and moisture — the cysteine thiol is highly susceptible to oxidation. Reconstitute in degassed buffer and minimize air exposure. Add chelators (EDTA) where appropriate to limit metal-catalyzed oxidation.
- Glutathione is the most abundant intracellular antioxidant. It is studied in oxidative stress models, redox biology, drug detoxification (Phase II conjugation), and as a substrate for glutathione peroxidase and S-transferase research.
- Glutathione is sold as a dietary supplement in some jurisdictions but is not an approved therapeutic for any specific medical condition by FDA. The research-grade material from Peptra Labs is supplied for laboratory research only.
