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。

X6 3?,large specific surface area and adsorbent capacity However,most molecules and hydrated ions can not enter the aperture pass because of their size over the aperture diameter of palygorslote except less simple ones Furthermore,Palygorskite adsorbs water molecule choosingly In most cases the absorbing of palygorskite is by its outside surface that works in the form of colloid and ion exchange other than i...

但是由于凹凸棒石孔道直径小于大多数分子及水合离子的直径，除少数简单分子和离子外，多数分子和离子都不能进入凹凸棒石孔道，而且凹凸棒石选择性吸附水分子，因而在多数情况下，凹凸棒石对吸附质的吸附不是内表面吸附，而是外表面吸附。并且外表面吸附是胶体和离子交换吸附。本文阐述了凹凸棒石的孔道直径、吸附选择性、体系pH 值及凹凸棒石和蒙脱石胶体颗粒的互相作用对凹凸棒石吸附性能应用的制约。
