L-Methionine Powder Usage and Synthesis.

L-Methionine is an essential amino acid for the nutrition of human and animal body, commonly used in the preparation of compound amino acid infusion, or the treatment of acute hepatitis, cirrhosis of the liver disease, as well as the antidote for drugs.

DL-Methionine is used in large quantities in the compound feed of cattle, pigs and chicks. Its metabolism is associated with cysteine. In prokaryotes formylated methionine is the starting amino acid for protein biosynthesis.

It can also be converted to s-adenosylmethionine by ATP activation and participate in the synthesis of creatine and choline as a methyl donor. Young rats cannot grow and develop normally without methionine. The main physiological function of methionine is to supply methyl.

It participates in the biochemical reaction of methyl transfer in vivo by providing a methyl group (-CH3), which is needed to supply methyl in the process of choline and creatine synthesis, and is also needed to supply methyl for methylation in certain protein molecules such as lysine, histidine and arginine, and is also needed to provide methyl for methylation of free carboxyl groups on protein molecules.

Methionine-rich foods include meat, fish, poultry and eggs, and mixed with legumes and cereals can play a complementary role to protein.

Uses and functions of L-Methionine.

Amino acid drugs, nutritional supplements. Used for liver cirrhosis and fatty liver. In addition, it is used as feed additives in large quantities to improve the quality of feed, increase the utilisation rate of natural proteins and promote the development of animals. For example, DL-methionine can improve the egg production of chickens, increase the weight of pigs and milk production of cows. Adverse reactions: Contraindicated in hepatic coma.

Nutritional supplement. One of the essential amino acids. Because the price is higher than DL-methionine but the effect is equal, so commonly used DL-methionine.

Used in biochemical research and nutritional supplements, also used in pneumonia, hepatic cirrhosis and fatty liver and other auxiliary treatment.

Characteristic of L-Methionine.

White flaky crystals or crystalline powder, peculiar odour, slightly sweet. mp280-282°C (decomposition), non-spinning, stable to heat and air, unstable to strong acid, can lead to demethylation. Soluble in water (3.5%, 25 ℃), dilute acid and dilute alkali solution, very difficult to dissolve in ethanol, insoluble in ether. Isoelectric point 5.74.

Pharmacodynamics of  Bulk L-Methionine Powder.

Methionine is a sulphur-containing amino acid. The synthesis of choline in the body requires methionine to supply methyl, and choline is a component of lecithin, which is an indispensable substance for fat transport out of the liver and removal of intrahepatic fat deposits, so methionine also has the lipotropic effect of choline.

In addition, methionine in the body Chemicalbook to supply sulfur to synthesise non-exogenous amino acid deaminic acid, and the latter has a detoxification effect, so this drug is clinically lipotropic hepatoprotective drugs for fatty liver and chronic hepatitis and cirrhosis accompanied by fatty infiltration. Clinically, methionine can also be used as an auxiliary treatment drug for alcohol and sulfonamide poisoning.
