Product Detail

Usage:

L-methionine is a sulfur-containing essential L-amino acid that is important in many body functions. Methionine is a dietary indispensable amino acid required for normal growth and development of humans, other mammals, and avian species. In addition to being a substrate for protein synthesis, it is an intermediate in transmethylation reactions, serving as the major methyl group donor.It must be obtained from diet and food sources since it is unable to be biosynthesized in the body. The minimum daily requirement of L-methionine for an adult male is 13 milligrams per kilogram of body weight. This quantity is normally easy to obtain from a complete diet.
Methionine is accepted as the metabolic precursor for cysteine. Only the sulfur atom from methionine is transferred to cysteine; the carbon skeleton of cysteine is donated by serine. (PMID: 16702340).It helps the body produce SAMe (S-Adenosyl-L-methionine), which has been used to treat psychiatric illnesses, infertility, liver problems, premenstrual disorders, and musculoskeletal conditions. Studies on SAMe have shown that it is as effective as tricyclic antidepressants in alleviating depression.
Ongoing studies that show promise are also being conducted to determine how effective L-Methionine may be for treating HIV/AIDS, liver damage, Parkinson’s disease, and urinary tract infections.

L-Methionine is used for feed additives.One composition of amino acid infusion. It is an essential amino acid for human body. And it is also used as food additive.

1. Selenium Methionine has anti-cancer effects. Human selenium deficiency is prone to liver cancer, lung cancer, stomach cancer, esophageal cancer, kidney cancer, prostate cancer, bladder cancer, cervical cancer, and leukemia.
2. Selenium Methionine has an antioxidant effect. Selenium is the best anti-aging substance. If the body lacks selenium, it will be “no longer young” and will lead to premature aging;
3. Selenium Methionine can enhance human immunity. Lack of selenium reduces the body’s immunity.
4. Selenium Methionine has the effect of antagonizing harmful heavy metals. Selenium deficiency is likely to cause symptoms of heavy metal poisoning such as lead, arsenic and cadmium.
5. Selenium Methionine can regulate the absorption and utilization of vitamin A, vitamin C, vitamin E and vitamin K. Selenium deficiency can cause diseases such as myopia, cataract, retinopathy, fundus diseases, and age-related macular degeneration.
6. Selenium Methionine has the function of regulating the synthesis of proteins. Lack of selenium can cause protein energy deficiency malnutrition, chromosomal damage and so on.
7. Selenium Methionine can enhance reproductive function. Lack of selenium can cause the emission of sperm to be blocked, sperm motility is low, deformity occurs, the conception rate is reduced, and the incidence of uterine inflammation is increased.
