Descriptions

Methionine is an essential nonpolar amino acid, and a lipotropic. Methionine and cysteine are the only sulfur-containing proteinogenic amino acids. The methionine derivative S-adenosyl methionine (SAM) serves as a methyl donor. Methionine plays a role in cysteine, carnitine and taurine synthesis by the transsulfuration pathway, lecithin production, the synthesis of phosphatidylcholine and other phospholipids. Improper conversion of methionine can lead to atherosclerosis. Methionine, a chelating agent, is one of only two amino acids encoded by a single codon (AUG) in the standard genetic code (tryptophan, encoded by UGG, is the other). The codon AUG is also significant, in that it carries the Start message for a ribosome to begin protein translation from mRNA. As a consequence, methionine is incorporated into the N-terminal position of all proteins in eukaryotes and archaea during translation, although it is usually removed by post-translational modification.

Methionine is an essential nonpolar hydrophobic amino acid. It provides sulfur for other sulfur-containing compounds and is important in the transfer of methyl groups. Methionine is important in cysteine, carnitine, and taurine synthesis by the transsulfuration pathway, lecithin production, and the synthesis of phosphatidylcholine and other phospholipids.(Information from Wikipedia 9/15/06).
