It caused aggregation of purple membrane fragments at very low concentration. This effect might be attributed to its positive charges because cationic surfactant DTAB acted the same. On the other hand, melittin seemed to have behavior similar to CHAPS which has a rigid cholane ring,both had little effect on the conformation of retinal chromporphores.In consideration of the two-dimensional crystalline structure of purple membrane,melittin may form a rigid conformation such as α-helix on the surface of the membrane.

通过与三种在结构和电荷上不同的表面活性剂与紫膜的作用相比较，可以年出蜂毒作为带正电荷的分子与同样带正电的表面活性剂DTAB在引起紫膜凝聚方面表现相同；但在对紫膜可见光区的吸收光谱和圆二色谱的影响上却与具有刚性结构的CHAPS相似，表明蜂毒可在紫膜表面以一种刚性较大的构象存在，不能进入膜蛋白流水区的深层。

利用电导率的这一转折性变化，建立起了复合作用电导滴定法测定共聚物P(AM- co -NaAMPS)分子链中磺酸盐单体NaAMPS含量的新方法。

We could draw a conclusion that microemulsion solubilization was effected with both the total amount of surfactant and cosurfactant on the interfacial film of microemulsion and confusable degree of interfacial film of microemulsion.

结果发现：当微乳界面膜上的表面活性剂和助表面活性剂总量增多，则相应的微乳体系增溶水量较大；微乳界面膜的混乱度增大，柔性增大，使得微乳界面膜易于弯曲，使微乳易于形成规整的球体，相应的微乳增溶水量较大。
