Abstract The partial molar volumes, V 2 ∘ , and partial molar heat capacities, C p , 2 ∘ , at infinite dilution have been determined for the compounds N -acetylasparaginamide, N -acetylglutaminamide, N -acetyltyrosinamide, and N -acetyllysinamide monohydrochloride in aqueous solution at T = (288.15, 298.15, 313.15, and 328.15) K. These results, along with the literature data for the compound N -acetylglycinamide
摘要 在无限稀释条件下,测定了化合物 N-乙酰天冬酰胺、N-乙酰谷氨酰胺、N-乙酰酪氨酸酰胺和 N-乙酰赖氨酰胺单盐酸盐水溶液的偏摩尔体积 V 2 ∘ 和偏摩尔热容 C p , 2 ∘ 。 T = (288.15, 298.15, 313.15, 和 328.15) K 时的溶液。这些结果,连同化合物 N-乙酰甘氨酰胺的文献数据,已被用于计算氨基酸侧链对热力学性质的贡献。将这些侧链贡献与使用小肽作为侧链模型化合物获得的贡献进行比较。
