Description

L-methionine is the L-enantiomer of methionine. It has a role as a micronutrient, a nutraceutical, an antidote to paracetamol poisoning, a mouse metabolite and a human metabolite. It is a L-alpha-amino acid, a methionine, an aspartate family amino acid and a proteinogenic amino acid. It is a conjugate base of a L-methioninium. It is a conjugate acid of a L-methioninate. It is an enantiomer of a D-methionine. It is a tautomer of a L-methionine zwitterion.
