摘要： 本文以带疏水侧链的丙氨酸为研究对象, 在298.15 K下测定其在LiNO3, NaNO3, KNO3, NaClO4及Na2SO4水溶液中的溶解焓, 探讨了不同种类的阳离子和阴离子对迁移焓的影响, 为揭示蛋白质与含氧酸盐水溶液的相互作用提供了有用信息.

关键词: 迁移焓, L-丙氨酸, 含氧酸盐

Abstract: Enthalpies of solution of L-alanine in water and aqueous solutions of LiNO3, NaNO3, KNO3, NaClO4 and Na2SO4 were determined at T=298.15 K by a RD496-Ⅱ microcalorimeter. The transfer enthalpies (ΔHtr) of L-alanine from water to aqueous solutions of salts were derived and discussed in terms of the electrostatic interaction and the structural interaction.

Key words: Transfer enthalpy, L-Alanine, Oxacid salt
