What is L-Tyrosine?
L-tyrosine is an optically active form of tyrosine having L-configuration. It has a role as a micronutrient, a nutraceutical, an EC 1.3.1.43 (arogenate dehydrogenase) inhibitor and a fundamental metabolite. It is a L-alpha-amino acid, a tyrosine, an erythrose 4-phosphate/phosphoenolpyruvate family amino acid and a proteinogenic amino acid. It is functionally related to a L-tyrosinal. It is a conjugate base of a L-tyrosinium. It is a conjugate acid of a L-tyrosinate(1-). It is an enantiomer of a D-tyrosine. It is a tautomer of a L-tyrosine zwitterion.
