Dmethionine
Dmethionine, or D-methionine, is the D-enantiomer of the essential amino acid methionine. Like methionine, it contains a thioether side chain and has the chemical formula C5H11NO2S, but its configuration at the alpha carbon is the mirror image of the naturally occurring L-methionine.
In biology, protein synthesis in humans and most organisms uses the L-form of amino acids. Consequently, D-methionine
D-methionine is produced and sold in pure form or as part of racemic DL-methionine. In agriculture and
Safety and regulation of D-methionine-containing products follow the same general considerations as other amino acid supplements
