Description :

It 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. It 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, but only reduced glutathione has physiological activity.
