residue bound to the dihexadecylamine component (N+C5HisAla2C16) afforded tubular aggregates in the aqueous dispersion. The hydrolysis of enantiomeric esters of various hydrophobic nature, which was carried out in the single-walled vesicles, showed relatively small enantioselectivity. The reasons for...
合成了四种具有二肽片段的两亲物,其由一个组氨酰残基和另一个氨基酸残基组成,以及双链片段的二十六烷基部分(N+C5AlaHis2C16、N+C5LeuHis2C16、N+C5PheHis2C16 和 N+C5HisAla2C16)。它们的聚集体形态通过电子显微镜和差示扫描量热法表征。具有与二十六胺组分(N+C5AlaHis2C16、N+C5LeuHis2C16、N+C5PheHis2C16)结合的组氨酰残基的两亲物在水分散状态下形成多壁和单壁聚集体,而它们的超声处理溶液仅涉及单壁囊泡。另一方面,具有与二十六胺组分 (N+C5HisAla2C16) 结合的丙氨酰残基的两亲物在水分散体中提供管状聚集体。在单壁囊泡中进行的各种疏水性对映体酯的水解显示出相对较小的对映选择性。原因...
