Details:

Methionine is a sulfur-containing non-polar aliphatic amino acid, also known as methionine, which is one of the essential amino acids for human body, abbreviated as Met and M. Glycogenic essential amino acids. It was isolated from casein in 1922. It is the only amino acid with a thioether structure. There are l-body and dl-body. Natural products are l-body. The relative molecular mass is 149.21. Has a special smell. Slightly sweet. L-Methionine is an essential amino acid for human and animal nutrition. It is often used to prepare compound amino acid infusion, or as a drug for treating acute hepatitis and cirrhosis, and as an antidote for drugs. DL-methionine is widely used in compound feed for cattle, pigs and chickens. Its metabolism is linked to cysteine. Formylated methionine in prokaryotes is the starting amino acid for protein biosynthesis. It can also be converted into s-adenosylmethionine by ATP activation, and participate in the synthesis of creatine and choline as a methyl donor. Young mice lacking methionine can not grow normally. The main physiological function of methionine is to supply methyl groups. It participates in the biochemical reaction of methyl transfer in the body by providing a methyl group (-CH3). It is required to supply a methyl group during the synthesis of choline and creatine. Lysine, histidine and Arginine also needs it to provide methyl groups for methylation, and free carboxyl groups on protein molecules also need it to provide methyl groups for methylation. Foods rich in methionine are mainly meat, fish, poultry, and eggs, and mixed with beans and cereals can play a complementary role in protein.

1. Amino acid drugs, nutritional supplements. For liver cirrhosis and fatty liver. In addition, it is widely used as a feed additive to improve the quality of feed, increase the utilization rate of natural protein and promote the development of animals. For example, DL-methionine can increase the egg production of chickens, increase the weight of pigs, and increase the milk production of dairy cows. Adverse reactions: Contraindicated in hepatic coma.
2. Nutritional supplements. One of the essential amino acids for the human body. Because the price is higher than DL-methionine and the effect is equal, DL-methionine is commonly used.
3. Used in biochemical research and nutritional supplements, also used in adjuvant treatment of pneumonia, liver cirrhosis and fatty liver, etc.
