D-tyrosine is the D-form amino acid of tyrosine. It is a non-essential amino acid. In animals, it can be de novo synthesized from phenylalanine. It is also the precursor of epinephrine, thyroid, hormones and melanin. Specially, study has shown that it can be taken s a chiral precusor to potent inhibitors of human Nonpancreatic secretory phospholipase A 2(IIa) with strong anti-inflammatory activity. It can also be used as a starting material for the preparation of anisomycin.

D-Tyrosine, the stereoisomer to L-Tyrosine (T899975), is an amino acid used in various organic syntheses for antibiotics. It is used in the synthesis of (-)-anisomycin, as well as BATSI (boronic acid
transition state inhibitors) which act on β-lactamases. It has also been studied as an inhibitor of microbial growth on surfaces, reducing microbial attachment to hydrophillic glass and hydrophobic po
lypropylene surfaces. | [Definition]

D-Tyrosine, as a dietary supplement, has the potential to enhance cognitive function, improve mood, and support overall mental health. It is also used in the synthesis of various important biomolecules, including melanin, which is essential for skin and hair pigmentation. | [reaction suitability]
