Structureactivity relationships and response features for amino acids in fish taste
Department of Oral Physiology, Kagoshima University Dental School 1Biological Institute, College of Liberal Arts, Kagoshima University Kagoshima 890, Japan
Recent investigations of amino acid taste responses in fish are reviewed, with emphasis on structureactivity relationships, receptor types and response enhancements. High stereospecificity of taste receptors in fishes is evidenced by response to L-amino acids of low mol. wt containing three to four carbon atoms, along with L-arginine, a six-carbon positively charged amino acid. Enantiomers are generally nonstimulatory. Attention is also informatively given to cross adaptation, synergistic and mixture experiments.
