What is L-Glutathione ?
Glutathione (GSH) is an important antioxidant in plants, animals, fungi, and some bacteria and archaea, preventing damage to important cellular components caused by reactive oxygen species such as free radicals, peroxides, lipid peroxides and heavy metals. It is a tripeptide with a gamma peptide linkage between the carboxyl group of the glutamate side-chain and the amine group of cysteine (which is attached by normal peptide linkage to a glycine).Glutathione exists in both reduced (GSH) and oxidized (GSSG) states.
Our Types of Glutathione:
Currently,we have Food grade,cosmetic grade,and medical grade glutathione,among of them,cosmetic grade glutathione is the raw material of injection glutathione.
Main medical functions of L-Glutathione:
1.It is the major endogenous antioxidant produced by the cells, participating directly in the neutralization of free radicals and reactive oxygen compounds, as well as maintaining exogenous antioxidants such as vitamins C and E in their reduced (active) forms.
2.It has a vital function in iron metabolism. Yeast cells depleted of or containing toxic levels of GSH show an intense iron starvation-like response and impairment of the activity of extramitochondrial ISC enzymes, followed by death.
3.It is used in metabolic and biochemical reactions such as DNA synthesis and repair, protein synthesis, prostaglandin synthesis, amino acid transport, and enzyme activation. Thus, every system in the body can be affected by the state of the glutathione system, especially the immune system, the nervous system, the gastrointestinal system, and the lungs.
Main cosmetic functions of L-Glutathione:
Glutathione is a tripeptide molecule found in mammalian bodies. It plays an important role in skin lightening ability. In addition to it ,glutathione prevented oxidative damage to the skin. Research results show that glutathione inhibits the actual production as well as agglutination of melanin by interrupting the function of L-DOPA. Another study found that glutathione inhibits melanin formation by direct inactivation of the enzyme tyrosinase by binding and chelating copper within the enzyme’s active site.
