Product Name: High Density L-Glutathione Reduced (GSH) 70-18-8 Grade Standard: Medicine Grade Function: Antibiotic and Antimicrobial Agents Apperance: White Crystalline Powder Origin: China Product Description Product Description:L-Glutathione Reduced (GSH) is a tripeptide which consists of glutamic acid, cysteine, and glycin. And it comprises a major portion of cellular nonprotein thiols, plays a central role in a diverse group of cell metabolic functions.Glutathione is soluble in water, dil alcohol, liq ammonia, dimethylformamide, not in grain alcohol, aether and acetone. Its solid is relative stable. And its solution is easily oxidized in the air. Two molecules also the lively reduced glutathione-condensation of the disulfide bonds, are oxidized glutathione (GSSG).Glutathione is widely applied to food, pharmaceutical, cosmetic and other fields.Application:1. Enhancing the immune system: Body' s immune activity, involving unimpeded multiplication of lymphocytes and antibody production, requires maintenance of normal levels of glutathione inside the lymphocytes. 2. Antioxidant and free radical scavenger: Glutathione plays a central protective role against the damaging effects of bacteria, viruses, pollutants and free radicals. 3. Regulator of other antioxidants: Without glutathione, other important antioxidants such as vitamins C and E cannot do their job adequately to protect your body against disease. 4. Detoxifying agent: Another major function of glutathione is in the detoxification of foreign chemical compounds such as carcinogens and harmful metabolites. 5. Skin whitening: Dermatologists prescribe Glutathione for its only side effect: Whitening of dark skin. People with darker skin tone report that taking Glutathione capsules along with vitamin C for three to six months or more actually lightens the color of their skin.Advantage:1.
