Glutathione oxidized by MP Biomedicals is a high purity cofactor. Glutathione or GSH, is an important antioxidant present in plants, animals, fungi, and some bacteria and archaea. This preparation is available as a white crystalline powder which is soluble in water. This molecule 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. It is capable of preventing damage to important cellular components caused by reactive oxygen species such as free radicals, peroxides, lipid peroxides, and heavy metals. CAS No. 27025-41-8 Quantity Provided: 500 mg per pack Molecular Formula: C20H32N6O12S2 Molecular Weight: 612.64 Soluble in water Glutathione is widely used in chemical and biological sectors. in-vivo, Glutathione disulphide (GSSG) is reduced back to glutathione (GSH) via the NADPH-dependent enzyme glutathione reductase. The ratio of GSH to this GSSG is often used to measure the level of oxidative stress in cells, with higher concentrations of GSSG implying more oxidative stress. The content of glutathione in the first raw form of wine (must), determines the browning, or caramelizing effect, during the production of white wine.
