Research-Grade Glutathione Peptide | High-Quality Chemical | CAS Number 70-18-8 | Lyophilized Powder

Glutathione (GSH), a tripeptide composed of glutamic acid, cysteine, and glycine, is present in nearly all living cells, with especially high levels in the liver. As the body's most essential and powerful endogenous antioxidant, it functions as a cellular "environmental guardian," eliminating oxidative waste such as free radicals generated during metabolism and preserving the cell's redox balance.
Containing active thiol (-SH) groups, glutathione's key functional sites readily bind with toxins and drugs, forming two main forms: the reduced form (G-SH) and the oxidized form (G-S-S-G). Under normal physiological conditions, the reduced form is predominant. It is mainly produced through the body's own metabolic pathways rather than relying on external sources like food or supplements, making its concentration a marker of the cell's capacity for self-repair and detoxification.
Glutathione directly scavenges free radicals, delays cellular aging, and helps regenerate vitamins C and E, enhancing their antioxidant effects. In the liver, it plays a vital role in metabolism by binding with drugs, alcohol, heavy metals (such as lead and mercury), and other harmful substances, converting them into harmless compounds for elimination. It also supports immune function by regulating cytokines and signaling pathways that activate immune cells. Furthermore, glutathione protects mitochondria—the energy-producing structures in cells—from oxidative damage and is essential for the normal metabolism of carbohydrates, fats, and proteins.
