Abstract

The time course of transformation between P' beta phase ad L' beta phase in multilamellar dimyristoylphosphatidylcholine vesicle containing 50% water was followed by small-angle X-ray diffraction. The transformation of P' beta leads to L' beta was 90% complete at 7 min after the temperature jump, although imperfections remained for a long time. Transformation in the opposite direction was fast as compared with P' beta leads to L' beta.

摘要

通过小角X射线衍射跟踪了含有50%水的多层二肉豆蔻酰磷脂酰胆碱囊泡中P'β相和L'β相之间转变的时间进程。从P'β相转变为L'β相在温度跃升后7分钟时90%完成,尽管缺陷会长期存在。与从P'β相转变为L'β相相比,相反方向的转变很快。
