生物体液可看作是由多种离子与氨基酸、蛋白质组成的混合电解质溶液,研究电解质或离子与这些氨基酸、蛋白质间的相互作用对了解生物体液内复杂的作用机理,揭示许多生命现象具有重要意义。1978年以来,Kelley采用有液体接界的电池研究了几种氨基酸或肽与一些碱金属氯化物的相互作用自由能,为研究电解质与氨基酸、蛋白质间的相互作用奠定了基础。研究溶质的迁移热力学性质是了解溶质-溶剂间相互作用以及溶液微观结构的常用手段。以氨基酸水溶液作为含水离子溶剂,用电动势法研究电解质从水到该溶液中的迁移热力学性质,进而研究电解质与氨基酸间的相互作用是可行的,目前这方面的研究工作很少见文献报导。本文通过测定电池:
The biological fluid can be regarded as a mixed electrolyte solution composed of a variety of ions and amino acids and proteins. Studying the interaction between electrolytes and ions and these amino acids and proteins is of great significance for understanding the complex mechanism of action in biological fluids and revealing many life phenomena . Since 1978, Kelley has studied the free energy of the interaction of several amino acids or peptides with some alkali metal chlorides using a liquid junction cell, laying the foundation for the study of the interaction between electrolytes and amino acids and proteins. Studying the thermodynamic properties of solute transport is a common means of understanding solute-solvent interactions and solution microstructures. It is feasible to study the interaction between electrolytes and amino acids by using electromotive force method to study the thermodynamic properties of migration of electrolytes from water to the solution by using amino acid aqueous solution as a water-containing ionic solvent. It is seldom reported in the literature at present. This article by measuring the battery:
