Abstract

L-Tyrosine and L-phenylalanine were incubated with decarboxylases and the resulting amines were detected with an amine-sensitive membrane electrode. The detection limit of L-tyrosine was 20 M. This limit was superior to that of an L-tyrosine electrode constructed from L-tyrosine decarboxylase and a carbon dioxide gas-sensing electrode.
