Explain:
1. Glutathione is a tripeptide which is composed of glutamic acid, cysteine and glycine and contains sulfhydryl groups. It has the functions of delaying aging, enhancing immunity, antioxidation and integrated detoxification.
2. Glutathione exists widely in animals and plants, and plays an important role in organisms. The content in baker's yeast, wheat germ and animal liver is very high, up to 100~1000 mg/100g, and 26~34 mg/100g in human blood.
3. Physiological function
① Detoxication: combine with poisons or drugs to eliminate their toxic effects;
② Participate in redox reaction: as an important reducing agent, participate in many redox reactions in vivo;
③ Protect the activity of sulfhydryl enzyme: keep the active group of sulfhydryl enzyme - SH in reducing state;
④ Maintain the stability of erythrocyte membrane structure: eliminate the damage of oxidant to erythrocyte membrane structure.
4. Action mechanism
As an important intracellular metabolic regulator, GSH is not only the cofactor of glyceraldehyde phosphate dehydrogenase, but also the coenzyme of glyoxalase and malose dehydrogenase. It participates in the body's tricarboxylic acid cycle and sugar metabolism, and can activate a variety of enzymes, such as sulfhydryl (SH) enzyme-coenzyme, so as to promote the metabolism of sugar, fat and protein.
