Description
white to off-white powder
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.|A non-essential amino acid. In animals it is synthesized from PHENYLALANINE. It is also the precursor of EPINEPHRINE; THYROID HORMONES; and melanin.

D-Tyrosine Use and Manufacturing
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 尾-lactamases. It has also been studied as an inhibitor of microbial growth on surfaces, reducing microbial attachment to hydrophillic glass and hydrophobic polypropylene surfaces.
