Poduct Name L-Glutathione Reduced Other Name Glycine, L-�³-glutamyl-L-cysteinyl Cas No. 70-18-8 MF C10H17N3O6S Appearance Powder Color White Purity 99% Min Package 1kg/aluminum foil bag; 25kg/drum Introduction of L-Glutathione Reduced: Glutathione (GSH) is named Reduced glutathione or L-Glutathione Reduced ,an important antioxidant in plants, animals, fungi, and some bacteria and archaea,a white crystalline powder. It is atripeptide 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.Thiol groups are reducing agents, existing at a concentration around 5 mM in animal cells. Glutathione reduces disulfide bonds formed within cytoplasmicproteins to cysteines by serving as an electron donor. In the process, glutathione is converted to its oxidized form, glutathione disulfide (GSSG), also called L-glutathione. Application of L-Glutathione Reduced : 1.L-Glutathione Reduced has elimination function of lipid peroxide and grease resistance to oxidation. And has anti-lipid oxidation. It can also prevent flavor nucleotides (inosinic acid, guanylic acid) food (fish cake, sausages, sauces, etc) lose their fresh flavor nucleotides in decomposing. Besides, it can strengthen the food flavor, and greatly extend the shelf life of food. 2.Add L-Glutathione Reduced into the canned fruit, it can prevent fruit browning; Add to dairy product, it can effectively preventenzymatic and non enzymatic browning. 3.L-Glutathione Reduced can be used as a flavoring agent in various processed foods. It also has the effect of enhancing flavor when added to meat and cheese. 4.L-Glutathione Reduced has the function of protecting the liver, inhibiting formation of fatty liver. Liver protection agent.Owing to its broad spectrum of physiological function, it can be widely used in the food,especially in anti-aging, enhance immune function and anti-tumor functional food base, enhance nutrition, additives and so on.
