Abstract

In rod outer segments, most lipids are phospholipids. Among the fatty acid chains of these phospholipids, half are polyunsaturated. Despite their tendency to get oxidized, we have succeeded to purify those phospholipids by a preparative method and to measure their individual area-pressure isotherms at argon-water interface. The analysis of those isotherms reveals that membranes formed from these phospholipids must be highly fluid and should molecular movements in the membrane.

摘要

在视杆细胞外段,大多数脂质是磷脂。在这些磷脂的脂肪酸链中,一半是多不饱和脂肪酸。尽管它们易于氧化,但我们已成功通过制备方法纯化这些磷脂,并在氩 - 水界面测量它们各自的面积 - 压力等温线。对这些等温线的分析表明,由这些磷脂形成的膜必定具有高度流动性,且膜内应有分子运动。
