Abstract

D-tryptophan and L-tryptophan are two amino acids which are optical isomers. It was impossible to differentiate L-tryptophan from D-tryptophan in a previous report using a measuring technique of the membrane potential of a multichannel taste sensor with lipid membranes. In this work, the two amino acids were identified from each other using the resistance change of the lipid membranes by performing the impedance measurement.
