Structural formula: {0} (CAS {1})

Methionine is a sulfur-containing amino acid that is butyric acid bearing an amino substituent at position 2 and a methylthio substituent at position 4. It has a role as a Saccharomyces cerevisiae metabolite, a plant metabolite, an Escherichia coli metabolite, a Daphnia magna metabolite and an algal metabolite. It is a sulfur-containing amino acid and an alpha-amino acid. It is functionally related to a butyric acid. It is a conjugate base of a methioninium. It is a conjugate acid of a methioninate. It is a tautomer of a methionine zwitterion.
