Thermodynamic Roles of Solubility in Taste Responses of Amino Acids

Bitter, sour and sweet responses of amino acids were relatedto their solubilities S_w, which are virtually equal to the reciprocalsof activity coefficients at infinite dilution in water _w, andalso related to their excess partial molar entropies of transferTS_t^E.
