Abstract
Mathematical analysis of superthreshold responses to Na salts stimulation of tongue of rat suggest that the ions are attracted to some receptor molecules by weak physical forces. Calculated [DELTA]F values range from -1.37 to -1.23 kcal/mole. Temperature experiments indicate a positive [DELTA] S. Little change in magnitude of response to NaCl of pH 3.0 to pH 11.0 suggest binding of ions to polyelectrolyte containing phosphate or sulfate groups.
