Description of L-Methionine
MET is an α-amino acid that is used in the biosynthesis of proteins. It contains an α-amino group (which is in the protonated −NH3+ form under biological conditions), an α-carboxylic acid group (which is in the deprotonated −COO− form under biological conditions), and an S-methyl thioether side chain, classifying it as a non-polar, aliphatic amino acid. It is essential in humans, meaning the body cannot synthesize it and thus it must be obtained from the diet.
Methionine is coded for by the initiation codon meaning it indicates the start of the coding region and is the first amino acid produced in a nascent polypeptide during mRNA translation.

What is L-Methionine?
- With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives.
- One such product is MET which has developed particularly rapidly in recent years. Do you know about MET?
- The official answer:L-methionine, also known as MET, is the levorotatory form of methionine, with the chemical formula C5H11NO2S. Melting point 280-281℃. It is unstable to strong acids and can lead to demethylation.
What’s the application of L-Methionine?
Amino acid medicine, nutritional supplements. Used for hepatic steatosis and fatty liver. It is also used in large quantities as a feed additive to improve the quality of feed, increase the utilization of natural proteins Chemicalbook rate and promote the development of animals. For example, DL-methionine can increase the egg production of chickens, increase the weight of pigs and increase milk production of cows. Adverse effects: contraindicated in hepatic coma.
