Methionine amino acid classification
Methionine (abbreviated as Met or M; encoded by the codon AUG) is an α-amino acid that is used in the biosynthesis of proteins. It contains a carboxyl group (which is in the deprotonated −COO form under biological pH conditions), an amino group (which is in the protonated −NH 3 form under … Meer weergeven Methionine (symbol Met or M) (/mɪˈθaɪəniːn/) is an essential amino acid in humans.
