摘要
The enthalpies of solution of l-alpha-aspartic acid, l-alpha-glutamic acid, l-alpha-arginine, l-alpha-lysine, and l-alpha-histidine have been measured in aqueous ethanol solutions at 298.15 K. From the obtained experimental results, the standard enthalpies of solution of amino acids in water-ethanol solutions have been determined. These data were used to calculate the heterogeneous enthalpic pair interaction coefficients based on McMillan-Mayer's formalism. These values were interpreted in the terms of the ionic or no polar effect of the side chains of l-alpha-amino acids on their interactions with a molecule of ethanol in water.
