Abstract

The material on optical modelling of pretransition processes in liquid crystalline hydrated lipid phases is presented. Results of estimation of the model of monoclinic phase formation are in the poorer agreement with X-ray diffraction data than the model of kinks appearance in the aliphatic core of layers. Arguments are presented in favour of complicated character of molecular rearrangements in lipid-water phases in the pretransition region and impossibility at present to correlate structural and calorimetric data when estimating premelting phenomena.

摘要

本文介绍了液晶水合脂质相预转变过程的光学建模材料。与层状脂肪族核心中扭结出现的模型相比,单斜相形成模型的估计结果与X射线衍射数据的吻合度较差。文中提出了支持脂质 - 水相在预转变区域分子重排具有复杂性的观点,以及目前在估计预熔现象时无法将结构数据与量热数据相关联的观点。
