Glutathione (GSH) is a kind of small molecule peptide substance which exists widely in human cells. It is composed of glutamic acid, cysteine and glycine.
It has good antioxidant and immunomodulatory effects in the body, and is widely used in food, medicine, cosmetics and other fields, and the discovery of its anti-melanin generation properties has also promoted it to become a whitening agent.
Antioxidant – protects against aging
Modern medicine believes that free radicals are one of the main causes of aging.
Excessive free radicals produced by the body’s metabolism will damage the biofilm, invade the macromolecules of life, accelerate the aging of the body, and induce the production of tumors or atherosclerosis.
Glutathione plays an important role in the biochemical defense system of human body and has many physiological functions.
Its main physiological role is to remove free radicals in the human body, as an important antioxidant in the body, protect many proteins and enzymes in the molecules of sulfhydryl, so that enzymes maintain their biological activity. Glutathione supplier
The structure of glutathione contains an active sulfhydryl -SH, which easily dehydrogenated by oxidation, and this specific structure makes it the main free radical scavenger in the body.
When a small amount of H2O2 produced in the cell, GSH reduces H2O2 to H2O under the action of glutathione peroxidase, and itself oxidized to GSSG, which receives H to reduced to GSH under the action of glutathione reductase present in the liver and red blood cells, so that the free radical scavenging reaction in the body can continued.
Whitening – Purifying the skin
Glutathione itself is a small molecule peptide, which binds with copper ion on tyrosinase molecule, can inactivate tyrosinase activity and inhibit melanin production.
Reduce free radicals and peroxides, reduce the biochemical activity of melanocytes;
Interaction with dopa reduces melanin production;
Neutralize the toxicity of toxic substances of pigment cells, and protect pigment cells from necrosis and deterioration.
Glutathione is different from VC and nicotinamide in its whitening effect on the entire melanin production process, and is an excellent whitening ingredient.
Detoxification – Body purifier
Environmental pollution, stress, the addition of hormones and heavy metals in undesirable cosmetics, drugs, diseases… Our cells are attacked by toxins all the time.
Glutathione can detoxify carcinogens such as carbon monoxide, CO, heavy metals, organic solvents and epoxides, and can combined with them and excreted in vitro.
It has a protective effect on leukopenia caused by radiation, radiopharmaceutical or antitumor drugs.
It also detoxifies various carcinogens by helping liver metabolism, such as aflatoxin.
The detoxification effect of glutathione is mainly that the sulfhydryl group on cysteine its active group (often abbreviated as G-SH), which is easy to combine with some drugs (such as paracetamol) and toxins (such as iodoacetic acid, mustard gas, lead, mercury, arsenic and other heavy metals), so that it has an integrated detoxification effect.
The use of ingredients containing glutathione in skin care products can treat and relieve excessive amounts of heavy metals in the skin, as well as toxins in most dust.
Immune enhancer
Neutrophils, phagocytes and lymphocytes in the human body constitute the immune system in the human body. The human body has the ability of spontaneous immunity, that is, it can resist the invasion of foreign pathogenic substances, such as bacteria, viruses and parasites.
It can also solve the abnormal physiological changes in the body, such as the proliferation of cancer cells, so as to maintain the normal survival order and protect our health.
However, to maintain the normal operation of the immune system, immune cells must fully activated and differentiated, and glutathione (GSH) is playing a role in the full activation and differentiation of immune cells.
The human immune system is the body’s most amazing design for fighting viruses, and glutathione (GSH) is responsible for:
① Activated lymphocytes;
② Differentiation and proliferation of T cells and B cells, and make T cells with toxicity, in order to kill viruses or cancer cells.
Increasing glutathione levels inside cells is the most powerful weapon in boosting the immune system.
