Glutathione is a tripeptide compound formed by the condensation of glutamic acid, cysteine and glycine through peptide bonds. It is the most important low molecular mercaptan in mammalian cells under antioxidant stress. Discovered in 1921, the chemical structure was determined in 1930. Dr. Al Mindel, a famous American nutrition and health expert, called glutathione a triple-potency anti-aging amino acid, also known as nature’s antioxidant master. The appearance of glutathione is colorless, transparent, slender granular crystal, soluble in water, dilute alcohol, liquid ammonia, dimethylformamide, insoluble in water. Ethanol, ether and acetone.

Reduced glutathione (GSH) is a small molecule peptide, which is abundant in organisms, especially in hepatocytes. GSH protects hepatocyte membranes, promotes the activity of hepatic enzymes, and combines with many toxic chemicals to detoxify them. For drug poisoning, alcoholism and other causes of liver injury, liver cirrhosis and other diseases have a good effect.
