3-Fluoro-DL-tyrosine is a derivative of tyrosine, a fundamental amino acid for protein biosynthesis. 3-Fluoro-DL-tyrosineIt is effectively used as a substrate in enzyme assays and as a marker for protein labeling. Moreover, it functions as a model system for the study of tyrosine transfer reactions. Used to study the reaction mechanism and kinetics involved in tyrosine transfer from a donor molecule to an acceptor molecule.
