Description

D-Tyrosine, the stereoisomer to L-Tyrosine, 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 polypropylene surfaces.
