Abstract

Fluorescence characteristics of isomeric ortho-, meta- and para-tyrosine have been determined. Differences in fluorescence lifetimes, especially at pH 1, provide a possible method for detection of ortho-tyrosine. A modified mathematical expression provides a photophysical method of detecting and estimating ortho-tyrosine in a mixture with para-tyrosine and phenylalanine. A possible application of this method is discussed.
