Abstract

The saturated cholesteryl ester, cholesteryl 16-doxylstearate, is shown to incorporate into hydrated egg yolk lecithin multilayers in two distinct forms as visualized by electron spin resonance (ESR) spectroscopy. At concentrations less than 1 mole%, the ester is uniformly distributed in the membrane while at higher concentrations, patches of solid ester are formed.

摘要

饱和胆固醇酯，即胆固醇16 - 脱氧硬脂酸酯，通过电子自旋共振（ESR）光谱观察发现，它以两种不同形式掺入水合蛋黄卵磷脂多层膜中。在浓度低于1摩尔%时，该酯均匀分布于膜中，而在较高浓度时，则形成固态酯斑块。
