The dependence of the interfacial tension of a lipid membrane on the pH of the aqueous solution has been studied. Interfacial tension measurements of phosphatidylethanolamine (PE) were carried out. A theoretical equation is derived to describe this dependence in the whole pH range. A maximum corresponding to the isoelectric point appears both in the theoretical equation and in the experimental data.
研究了脂质膜的界面张力对水溶液pH值的依赖性。进行了磷脂酰乙醇胺(PE)的界面张力测量。推导了一个理论方程来描述在整个pH范围内的这种依赖性。在理论方程和实验数据中均出现了一个对应于等电点的最大值。
