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.
Feed additives:
L-Methionine is mainly used as feed nutritional supplements and one of the essential amino acids in the growth of animals, which is the "skeleton" amino acid in protein biosynthesis and main donor of methyl in animal body. L-Methionineplays a certain role in the process of synthesis of choline by adrenal hormone and fatty liver phospholipids during the process of metabolism of the animal in vivo. Lacking of L-Methioninein livestock and poultry will lead to poor development, weight loss, liver and kidney function decline, muscle atrophy, fur deterioration, etc.
L-Methionine is a sulfur amino acid and the second limiting essential amino acids for pigs. The utilization ratio of feed protein can be improved effectively if lysine and L-Methioninewere added in the feed appropriately. So the lysine and L-Methionineare called enhancer for protein feed. Naturally occurring L-Methioninehas two types: D type and L type two and their biological utilization rate is identical. Synthetic L-Methionineis a type DL compound of type D and type L. The biological potency of compound is the same as that of the single D or L-methionine. The appearance of DL methionine additive is white to pale yellow crystal or crystalline powder and insoluble in water and has slightly sweetness haste. The content of L-Methioninein feed of pig is generally from 0.05% to 0.1%.
L-Methionineas a nutritional supplement, the effect of the type L is the same as that of the type of DL (due to the type L transformed from the type DL). Feed additives; as the product and cysteine both belong to sulfur-containing amino acids, so a large amount of them exist in animal proteins. However, it belongs to limiting amino acids in plant proteins such as oats, rye, rice, corn, wheat, peanuts, soybeans, potatoes, spinach and other vegetable foods and the content is less than animal proteins.So it can be added to the above food to improve the balance of amino acids. In the past, sulphur-containing amino acids were thought to be only suitable for non-ruminants. But now the experiment has been proved that it is applicable to the non-ruminants. It is more suitable for chicken and pig feed. On the medical side, it can be used for infusion together with other amino acids. Also used as a culture medium during fermentatio
Pharmacodynamics:
L-Methionineis a sulfur-containing amino acid. Choline is synthesized in vivo by the L-Methioninesupplying the required methyl. And choline is a component of lecithin. Lecithin is an essential material for the removal of fat from the liver and the deposition of fat in the liver. So L-Methioninealso has an effect in choline lipotropic. In addition, L-Methioninein vivo supplies sulfur to synthesize non-exogenous amino acid Cys. The latter has the function of detoxification. Therefore, this medicine is used for the liver lipotropic in clinical , which is Suitable for fatty liver and chronic hepatitis and liver cirrhosis with fat infiltration. Clinical L-Methioninecan also be used as an adjuvant therapy drug for alcohol and poisoning.
