The Uses of D-Tyrosine

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.

The Uses of D-Tyrosine

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

What are the applications of Application

D-Tyrosine is D-Tyrosine is a non-essential amino acid. In animals it is synthesized from phenylalanine. It is also the precursor of epinephrine; thyroid hormones; and melanin.
