D-Tyrosine Chemical Properties,Uses,Production

Description

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.

Chemical Properties

white to off-white powder

Uses

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.

Uses

D-Tyrosine is synthesized from phenylalanine. It is also the precursor of epinephrine, thyroid hormones, and melanin.

Definition

ChEBI: D-tyrosine is an optically active form of tyrosine having D-configuration. It has a role as an Escherichia coli metabolite. It is a tyrosine and a D-alpha-amino acid. It is a conjugate base of a D-tyrosinium. It is a conjugate acid of a D-tyrosinate(1-). It is an enantiomer of a L-tyrosine. It is a tautomer of a D-tyrosine zwitterion.

benefits

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.
