Abstract
X-ray diffraction measurements show that the beta'-crystalline to liquid crystalline transitions of dipalmitoyl lecithin-water mixtures take place over temperature ranges of several degrees, and by the gradual disappearance of one crystalline state accompanied by the gradual appearance of the other. The narrowness of the low angle X-ray lines indicates that the two crystalline states exist in separate phases. At a given temperature, the liquid crystalline phase has the greater water content. The bilayers of the liquid crystalline phase are thinner than those of the beta'-crystalline phase while the distances between bilayers are essentially equal in the two phases.
摘要
X射线衍射测量表明，二棕榈酰卵磷脂 - 水混合物从β'-晶态到液晶态的转变发生在几个摄氏度的温度范围内，是通过一种晶态的逐渐消失伴随着另一种晶态的逐渐出现来实现的。低角度X射线线条的狭窄表明这两种晶态存在于不同的相中。在给定温度下，液晶相的含水量更高。液晶相的双层比β'-晶态相的双层更薄，而两相中双层之间的距离基本相等。
