DL-methionine
Sign in to savethumb|Methionine ball and stick model spinning Methionine (symbol Met or M) () is an essential amino acid in humans. Compared to other amino acids, methionine has particularly decisive biosynthetic roles. It is the precursor to the amino acid cysteine and the pervasive methylation agent rSAM. Methionine is required for protein synthesis, which is initiated by N-formylmethionine-sRNA.
AI overview
DL-methionine is a form of the amino acid methionine that your body needs to build proteins and carry out important chemical processes like methylation. It's particularly important because it serves as the starting point for making other amino acids and molecules that your cells rely on for basic functions.

Methionine was first isolated in 1921 by John Howard Mueller. It is encoded by the codon AUG. It was named by Satoru Odake in 1925, as an abbreviation of its structural description 2-amino-4-(methylthio)butanoic acid.
