Experimental Values

Partial molar volumes of the following mixtures, [Formula: see text](mix) were determined in water at 20 °C: (1) glutamic acid: glycine; (2) arginine:glycine; (3) arginine:glutamic acid; (4) arginine: aspartic acid; (5) lysine:glutamic acid, and (6) lysine: aspartic acid. Partial molar volumes of the mixtures calculated using [Formula: see text] of various ionic species of the amino acids agreed with the experimental values for systems 1 and 2, but were less than the experimental values for systems 3 to 6. The positive deviations, [Formula: see text] (mix), of the experimental values from the calculated values are discussed in terms of "specific interactions" between ionogenic side chains. The extent of interaction is greater in systems containing aspartic acid and/or arginine.
