Glutathione performance introduction
2021-12-21
Glutathione (GSH) is an important antioxidant in plants, animals, fungi, and some bacteria and archaea. It can prevent free radicals, peroxides, lipid peroxides, heavy metals and other reactive oxygen species from affecting important cell components. Injury plays an important role in the organism. Glutathione (glutathioneGSH) is a tripeptide containing sulfhydryl groups combined with glutamic acid, cysteine and glycine, which has antioxidant and integrated detoxification effects. Excessive free radicals produced by the body's metabolism will damage the biofilm, invade the life macromolecules, accelerate the body's aging, and induce the production of tumors or atherosclerosis. Glutathione plays an important role in the body's biochemical defense system and has many physiological functions. Its main physiological function is to remove free radicals in the human body, and as an important antioxidant in the body, it protects the sulfhydryl groups in many molecules such as proteins and enzymes. The structure of GSH contains an active sulfhydryl group -SH, which is easily oxidatively dehydrogenated. This specific structure makes it a major free radical scavenger in the body. For example, when a small amount of H2O2 is produced in the cell, GSH will reduce H2O2 to H2O under the action of glutathione peroxidase, and it will be oxidized to GSSG. GSSG is reduced by glutathione present in the liver and red blood cells. Under the action of enzymes, H is reduced to GSH, so that the scavenging reaction of free radicals in the body can continue. Glutathione can not only eliminate free radicals in the human body, but also improve human immunity. Glutathione maintains health, resists aging, and exerts greater effects on the delayed cells of the elderly than the young. Glutathione can also protect hemoglobin from oxidation by hydrogen peroxide, free radicals, etc., so that it can continue to perform its ability to transport oxygen normally. Part of the hemoglobin in red blood cells is oxidized to ferric iron by hydrogen peroxide and other oxidants, which converts hemoglobin into methemoglobin, thereby losing the ability to carry oxygen. Reduced glutathione can directly combine with hydrogen peroxide and other oxidants to generate water and oxidized glutathione, and it can also reduce methemoglobin to hemoglobin. There is a lot of glutathione in human red blood cells, which is of great significance to protect the sulfhydryl group of the protein on the red blood cell membrane in a reduced state and prevent hemolysis. Glutathione protects the -SH group in the enzyme molecule, which is conducive to the development of enzyme activity, and can restore the active function of the -SH group in the enzyme molecule that has been destroyed, so that the enzyme can regain its activity. Glutathione can also inhibit fatty liver caused by ethanol invading the liver. Glutathione has a strong protective effect on the symptoms of leukopenia caused by radiation and radiopharmaceuticals. Glutathione can combine with toxic compounds, heavy metal ions or carcinogens that enter the human body, and promote its excretion from the body to neutralize and detoxify.
