在（5、15、25、35和45）°C下，测量了氨基酸、L-天冬酰胺、L-谷氨酰胺、L-组氨酸、L-天冬氨酸盐、L-谷氨酸盐、L-赖氨酸单盐酸盐、L-精氨酸单盐酸盐和L-组氨酸单盐酸盐的稀水溶液中的密度和声速。这些氨基酸在无限稀释的偏摩尔体积和偏摩尔等熵压缩进行了评估和讨论的氨基酸侧链的带电基团和溶剂水之间的静电相互作用。
The densities and speeds of sound in dilute aqueous solutions of the amino acids, l-asparagine, l-glutamine, l-histidine, l-aspartic acid monosodium salt, l-glutamic acid monosodium salt, l-lysine monohydrochloride, l-arginine monohydrochloride, and l-histidine monohydrochloride, were measured at (5, 15, 25, 35, and 45) °C. Partial molar volumes and partial molar isentropic compressibilities of these amino acids at infinite dilution were evaluated and discussed in connection with the electrostatic interactions between the charged groups of amino acid side chains and solvent water.
