Glutatione Anti Aging Powder 70-18-8 Antioxidant Cosmetic Food Grade

Introduction   :

Glutathione GSH is a tripeptide containing sulfhydryl group combining glutamic acid, cysteine and glycine, which has antioxidant and integrative detoxification effects. The thiol group on cysteine is the active group of glutathione (glutathione is often short for G-SH), which is easy to combine with some drugs (such as paracetamol) and toxins (such as free radicals, iodoacetic acid, mustard gas, lead, mercury, arsenic and other heavy metals), and has an integrated detoxification effect. Therefore, glutathione (especially glutathione in liver cells) can participate in biotransformation, thereby converting harmful toxins in the body into harmless substances and excreting them out of the body. Glutathione also helps maintain normal immune system function.

There are two forms of glutathione: reduced glutathione (G-SH) and oxidized glutathione (G-S-S-G), and reduced glutathione predominates in physiological conditions. Tautometry between two types catalyzed by glutathione reductase. The coenzyme provides NADPH for sugar phosphate bypass metabolism.

Function :

Glutathione exists widely in animals and plants and plays an important role in living organisms. It is high in baker's yeast, wheat germ and animal liver, up to 100 ~ 1000mg/100g, 26 ~ 34mg/100g in human blood, 58 ~ 73mg/100g in chicken blood, 10 ~ 15mg/100g in pig blood. It was also high in tomato, pineapple and cucumber (12-33 mg/100g), but low in sweet potato, mung bean sprout, onion and mushroom (0.06-0.7 mg/100g).

Excessive free radicals generated by the body's new and old metabolism will damage the biofilm, invade the macromolecules of life, accelerate the aging of the body, and induce the generation of tumor or atherosclerosis. Glutathione plays an important role in the biochemical defense system in human body and has many physiological functions. Its main physiological role is to scavenge free radicals in the human body, as an important antioxidant in the body, protecting the sulfhydryl groups in many proteins and enzymes. The structure of GSH contains an active sulfhydryl group -SH, which is easily dehydrogenated by oxidation. This special structure makes GSH a major free radical scavenger in vivo. For example, when a small amount of H2O2 is generated in cells, GSH reduces H2O2 to H2O under the action of glutathione peroxidase, and itself is oxidized to GSSG. GSSG is reduced to GSH by H under the action of glutathione reductase existing in liver and red blood cells, so that the scavenging reaction of free radicals in the body can continue.

Glutathione can not only eliminate free radicals, but also improve human immunity. Glutathione is a health protective, anti-aging, and has a greater effect on the delayed cells of older people than in younger ones.

Glutathione also protects hemoglobin from oxidation by hydrogen peroxide and free radicals so that it can continue to transport oxygen properly. Under the action of oxidizing agent such as hydrogen peroxide, part of hemoglobin in red blood cells oxidizes to trivalent iron, so that hemoglobin is transformed into methemoglobin, thus losing the ability to carry oxygen. Reduced glutathione can not only directly combine with oxidants such as hydrogen peroxide to form water and oxidized glutathione, but also reduce methemoglobin to hemoglobin. There is a lot of glutathione in human red blood cells, which is of great significance to protect the thiol group of protein on erythrocyte membrane in the reduced state and prevent hemolysis.

Glutathione protects the -SH group in the enzyme molecule, which is conducive to the development of the enzyme activity, and can restore the activity function of the -SH group in the destroyed enzyme molecule, so that the enzyme can restore the activity. Glutathione also inhibits fatty liver caused by ethanol invasion of the liver.

Glutathione has a strong protective effect on leukopenia and other symptoms caused by radiation and radioactive drugs. Glutathione can combine with toxic compounds, heavy metal ions or carcinogens that enter the human body and promote their excretion to neutralize and detoxify.
