Glutathione is a tripeptide compound composed by the amino acid, glutamic acid (glutamate) and cysteine three amino acids. Dietary glutathione is found in fruits, vegetables, especially asparagus, avocados, walnuts, fish and meat.
Glutathione is called "antioxidants master", can help the body cells against oxidative damage, achieve the anti-aging purposes, is a common cosmetic raw material, in addition to its own effective antioxidant, it can also promote recycling use of other oxidants such as vitamin C and vitamin E. Thus, glutathione can contribute to prevent cancer and other diseases caused by oxidative damage. Glutathione also plays an important role in regulating immune cells, it is an effective antidote. Low levels of glutathione are related to hepatic dysfunction, immune system dysfunction, heart disease and premature aging. Glutathione is very important in the synthesis of DNA synthesis and repair, the synthesis of protein and prostate, amino acid transport. Several studies show that glutathione has anti-viral effect. The study found that glutathione can inhibit the activation of the AIDS virus, so that it’s benefit to AIDS carriers and patients.
Glutathione has not known deficiency symptoms, but some medical diseases - such as diabetes, low sperm count and hepatopathy are related to glutathione lacking. Heavy smokers are with lower glutathione levels in body, it is because certain chemicals in tobacco will increase the utilization of the human glutathione.
Daily therapeutic dose: the crowd had been confirmed that lack of glutathione should seek medical treatment, may be need intravenous or intramuscular injection. Glutathione supplier suggests that oral glutathione is not the best way to improve blood glutathione levels. One study found that healthy people taking 500 milligrams of vitamin C every day, after two weeks, the glutathione levels in the blood increased by 50%. Other nutritional compounds can promote glutathione levels include: alpha lipoic acid, glutamate, methionine, adenosylmethionine sulfide and whey protein.
Glutathione is a mercapto group-containing small molecule peptide, with important antioxidant role and integration detoxification effect. Glutathione is a tripeptide combined by glutamic acid, cysteine and glycine, the mercapto group on the cysteine is its reactive groups (so that glutathione often abbreviated as G-SH), easy to combine with iodoacetic acid, mustard gas (a gas), lead, mercury, arsenic and other heavy metal salt, thus have the integration detoxification effect. Glutathione (especially the liver cells’ glutathione) have a very important physiological role, that is integrate detoxification, can bind with certain drugs (such as paracetamol), toxins (such as free radicals, heavy metals) and so on, involved in biological transformation role, so that translate the body’s harmful poisons into harmless substances, excrete out of the body.
Glutathione also has reduction form (G-SH) and oxidized form (G-S-S-G) form two kinds, under physiological conditions, the reduced glutathione occupied the majority. Glutathione reductase catalyzes the interconversion between the two types. The coenzyme of this enzyme is the NADPH supplied by sugar phosphate metabolism.

The application of tungsten in various industries
Steel Industry Most of tungsten applied in the production of special steels. The widely used high-speed steel was containing 9-24% of tungsten, 3.8-4.6% of chromium, 1-5% of vanadium, 4-7% of cobalt, 0.7-1.5% of carbon.
Magic effects of coconut oil
According to records, coconut oil can be regarded as the nobility of skin care plant extracts. It was rich in exotic tension of tropical plants, which can enhance the contractile force of the pores, perfectly beautify and nourish the skin.
Exploring the Potentials of Nano-Aluminum Powder
Nano-aluminum powder, a material with remarkable properties due to its minuscule particle size, is revolutionizing various industries with its high reactivity and large specific surface area. Unlike its bulk counterpart, nano-aluminum powder begins to oxidize at a lower temperature of 550°C, compared to the 950°C oxidation point of ordinary aluminum. This lower ignition energy and full combustion without apparent cohesion make it a superior choice for applications requiring high energy and efficiency. The unique characteristics of nano-aluminum powder, such as faster burning rates and greater heat release, are largely influenced by its synthesis method, which determines its particle size, surface area, and shape.
