As a result, electrostatic interactions and hydrogen bond were identified to contribute to the affinity interaction, while hydrophobic interaction contributed little. Moreover, the importance of electrostatic interactions and hydrogen bond to the affinity changed with pH value.The effect of rate of mobile phase on the retention of insulin was researched and the dynamic adsorption isotherm was got by analyzing the breakthrough data with Langmuir equation.

通过调节流动相的pH值和离子强度，并使用尿素和乙二醇分别对吸附蛋白进行洗脱，详细研究了吸附效果最好的目标蛋白质与肽配基之间的亲和吸附机理，发现静电作用和氢键是二者之间产生亲和吸附的主要作用力，而疏水相互作用对该亲和几乎没有贡献。

本文尝试在离子交换层析的静电相互作用研究中引入计算机分子模拟技术，构筑合适的蛋白质-介质配基模拟表面，通过分子模拟计算表征相互作用的能量参数，从层析保留时间实验获得描述宏观分离行为的停留因子，实现微

Because the accumulation of flavonoids was the foundation of producing mottling on seed coat, the composition and changes of content of flavonoids were related to resistance level to seed coat mottling in mature seed.

类黄酮在种皮上的积累为形成斑驳构成了物质基础。成熟种子种皮中类黄酮配基的组成和含量变化与抗种粒斑驳的抗性相关。

The protein had the specificity on substrate recognition, which could decompose 3,4-dihydroxybenzoic acid to catechol but not 2,4-dihydroxy- benzoic acid to resorcin. The ligand at C-3 site of benzene ring had no effect on enzyme activity.

蛋白质还具有底物识别的特异性，能够催化3，4-二羟基苯甲酸转化为邻苯二酚，而不能催化2，4-二羟基苯甲酸转化为间苯二酚，这表明苯环上3'位的配基对酶活无影响。
