incorporation of 2H-labeled trans-diethylstilbestrol (DES) (1b) and its methyl ether derivatives (2a, 2b, and 3) into multibilayers of egg phosphatidylcholine was analyzed by means of deuterium nuclear magnetic resonance. A clear distinction was found between DES or its methyl ether derivatives incorporated into lipid bilayers and those precipitated in the aqueous phase, by taking into account the extent
通过氘核磁共振分析了将2H标记的反式己二烯雌酚(DES)(1b)及其甲基醚衍生物(2a,2b和3)掺入卵磷脂酰胆碱的多层结构的方式。通过考虑运动平均四极相互作用的程度,发现掺入脂质双层的DES或其甲基醚衍生物与在水相中沉淀的衍生物之间有明显的区别。因此,发现掺入多层中的这些化合物的相对比例按以下顺序降低:DES(1b)大于DES单甲基醚(2a和2b)大于DES二甲醚(3)。此外,我们证明了在这些化合物中,多层双层中的嵌入方式差异很大。
