Glutathione molecular weight of 307.33, melting point of 189~193 ℃ (decomposition), crystal is colorless transparent thin cylindrical in shape and isoelectric point of 5.93.It is soluble in water, dilute alcohol, liquid ammonia and methyl formamide, and insoluble in alcohol, ether and acetone.Organisms only with physiological activity, GSH and GSSG need to restore to play its important physiological functions.The GSH under high water activity is not easy to save, only controlling the water activity below 0.3 to long-term stability.Studies have found that in vitamin C (pH3.3) in aqueous solution containing GSH, with strong reducing effect of vitamin C, GSH no oxidation of solution for the GSSG, but the decomposition speed is accelerated;But in the vitamin C solution GSSG will not change as GSH, and save the stability is very good.And oral intake of GSSG in the upper small intestine can be restored as GSH, in the small intestine epithelial cell surface by gamma GTP (GSH is decomposed into glutamic acid and Cys-Gly) and the role of the dipeptide enzyme and is absorbed, can also play an important physiological function.
Glutathione is widely found in animals and plants, and the contents of the bread yeast, wheat germ and animal liver are very high,100~100 mg/1000 g;Content is also rich in human and animal blood, such as human blood contains 26~34 mg/100 g, chicken blood contains 58-73 mg/73 g, pig blood contains 10~15 mg/100 g, the dog blood contains 14~22 mg/100 g.Many vegetables, potato and corn also contains GSH .
1.Reduced glutathione is a kind of small molecular peptide, a large number of peptides in living organisms, especially in liver cells, protect the liver cell membrane, promote the role of liver enzyme activity, and with a number of toxic chemicals in combination with play the role of detoxification.To the drug poisoning, alcoholism and other causes of liver injury, disease such as cirrhosis of the liver have good curative effect. Usage
2.With antioxidant, scavenging free radicals, detoxification, enhance immunity, anti-aging, anti-cancer, anti radiation damage, and other functions.
3. Used as biochemical reagents,detoxification drugs, it is mainly used for the poisoning of heavy metals, acrylonitrile, fluoride, carbon monoxide and organic solvents.
