Glutathione is an important antioxidant in the human body, in the form of reduced glutathione (GSH) and oxidized glutathione (GSSG), of which GSH is composed of glutamic acid, glycine and cysteine through peptide bonding, and is synthesized in the liver in the largest amount.
Physiological function of glutathione
1, Antioxidant effect, prevent all kinds of liver disease
GSH can repair abnormal liver function by scavenging free radicals and lipid peroxides and improving antioxidant activity.
GSH can protect membrane sulfhydryl proteins and enzymes from oxidation. It can also reduce the damage of the cell membrane and maintain the integrity and stability of the liver cell membrane.
2, anti-aging
Glutathione can effectively delay cell senescence and accelerate cell regeneration.
Supplementation of GSH can increase or promote the secretion of human growth hormone (interleukin), which can regulate and slow the shortening of telomeres, prolong cell life, and effectively anti-aging.
3, Whitening, light spots
Directly inhibit the activity of tyrosinase, while cleaning up a large number of oxidizing free radicals, prevent free radicals from activating tyrosinase, it can also hydrolyze into cysteine, interfere with melanin synthesis, thus inhibiting melanin precipitation, regulating skin, playing a role in whitening and lightening spots.
The application of glutathione
1, Health care products
In addition to using its sulfhydryl group to integrate toxins such as heavy metals, fluoride, mustard gas,
glutathione can also prevent hepatitis, hemolytic diseases, as well as keratitis, cataracts, and retinal diseases.
2, Livestock, poultry, meat and seafood
Adding GSH to meat and seafood can effectively inhibit the decomposition of nucleic acid,
enhance flavor and extend the shelf life of food.
3, Condiments
It found that GSH mixed with L-glutamate sodium, cystine and xylose could produce unique beef flavor.
And glutathione and flavor nucleotides such as inosine, guanylic acid and sodium glutamate after mixing,
will form a strong meat flavor, can be used as flavoring agents and flavor agents in a variety of food processing.
