e, where x=0 to 2, in aqueous solution at 25^C. Values for V2^ at 25°C have also been determined for two neutral peptide derivatives N-acetylglycylglycinamide and N-acetylglycylglycylglycinamide. These V2°; and Cp,2°; results were used to estimate the partial molar volume and heat capacity of the backbone glycyl group, CH2CONH, of proteins in aqueous solution at 25°;C. The results obtained are compared
已经确定了在 25 ℃水溶液中,序列丝氨酰(甘氨酰)x甘氨酸的三个新肽(其中 x=0 到 2)在无限稀释时的偏摩尔体积 V2^ 和偏摩尔热容 Cp,2^ ^C。对于两种中性肽衍生物 N-乙酰甘氨酰甘氨酰胺和 N-乙酰甘氨酰甘氨酰胺,也已经确定了在 25°C 下的 V2^ 值。这些 V2°;和 Cp,2°;结果用于估计 25°C 水溶液中蛋白质的主链甘氨酰基 CH2CONH 的偏摩尔体积和热容量。将获得的结果与使用替代模型化合物的部分摩尔数据计算的结果进行比较。
