Abstract

It is shown, by infrared spectroscopy, that the packing in the gel phase of fully-hydrated dipalmitoyl phosphatidylcholine is not uniform over a large temperature range. With decreasing temperature, starting at that of the pretransition, there is a gradual change in the molecular packing of the acyl chains, from near hexagonal to orthorhombic of monoclinic.

摘要

红外光谱显示，在较大温度范围内，完全水合的二棕榈酰磷脂酰胆碱凝胶相中的堆积并不均匀。从预转变温度开始，随着温度降低，酰基链的分子堆积逐渐发生变化，从接近六方晶系转变为单斜晶系的正交晶系。
