It has recently been proposed that although small amphiphilic molecules partition into phospholipid vesicles this partition is reduced by a factor of 10(3)-10(4)-fold by the presence of proteins in biological membranes [Conrad & Singer (1979) Proc. Natl. Acad. Sci. U.S.A.76, 5202-5206 and (1981) Biochemistry20, 808-818]. However, the affinity with which 8-anilinonaphthalene-1-sulphonate partitions into, or binds to, Triton X-100 micelles and submitochondrial particles is very similar and therefore does not support this proposal.
最近有人提出,尽管小的两亲分子会分配到磷脂囊泡中,但由于生物膜中蛋白质的存在,这种分配会减少10³-10⁴倍[康拉德和辛格(1979年)《美国国家科学院院刊》76, 5202 - 5206以及(1981年)《生物化学》20, 808 - 818]。然而,8-苯胺基萘-1-磺酸盐分配到Triton X-100胶束和亚线粒体颗粒中或与之结合的亲和力非常相似,因此不支持这一观点。
