Glutathione (GSH) is an important antioxidant in plants, animals, fungi, and some bacteria and archaea. Glutathione is capable of preventing damage to important cellular components caused by reactive oxygen species such as free radicals, peroxides, lipid peroxides, and heavy metals.It is a tripeptide with a gamma peptide linkage between the carboxyl group of the glutamate side chain and the amine group of cysteine, and the carboxyl group of cysteine is attached by normal peptide linkage to a glycine.
L-Glutathione Reduced is a tripeptide which consists of glutamic acid, cysteine, and glycin. The L-Glutathione Enriched Yeast obtained via microbial fermentation, then obtain the L-Glutathione Reduced by modern technology’s separation and purification .It is an important functional factor,which has many functions, such as anti-oxidant, free radical scavenging, detoxification, enhance immunity, anti-aging, anti-cancer, anti-radiation hazards and others.
