Concentration−response curves and EC50 comparisons of wild-type and N172K mutated white-faced saki Tas2R16 for salicin (A) and helicin (B). Response curves of wild-type and N172K mutated Tas2R16 are represented by solid and dotted lines, respectively. **, Differences are significant at the 1% level (P < 0.01).
