D-Tyrosine, the stereoisomer to L-Tyrosine, is an amino acid used in various organic syntheses for antibiotics. It has also been studied as an inhibitor of microbial growth on surfaces, reducing microbial attachment to hydrophillic glass and hydrophobic polypropylene surfaces.

Function
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.
