Methionine is a sulfur-containing non-polar aliphatic amino acid, also known as methionine. It is one of the essential amino acids for the human body and is abbreviated as Met and M. Essential amino acids for sugar production. It was isolated from casein in 1922. It is the only amino acid with sulfide structure. There are l-body and dl-body. Natural products are l-body. Has a special smell. Slightly sweet. Stable to air and heat.

L-methionine is an amino acid necessary for the nutrition of humans and animals. It is often used to prepare compound amino acid infusions. It is also a drug for the treatment of acute hepatitis and cirrhosis, and an antidote for drugs. DL-methionine is widely used in compound feed for cattle, pigs and chickens. Its metabolism is linked to cysteine. In prokaryotes, formylated methionine is the starting amino acid for protein biosynthesis. It can also be activated by ATP and converted into s-adenosylmethionine, which acts as a methyl donor to participate in the synthesis of creatine and choline.
