Description
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.
