Abstract
13-C NMR spectra of sonicated phospholipid dispersions have been investigated with the aid of paramagnetic ions (Pr-3+) as shift reagents. This method permits discrimination between the outer and the inner surfaces of the vesicular membrane and gives a larger variety of signals than 1-H NMR. The lanthanide induced shifts have been found to depend on other ions present and on the lipid composition of the membrane.
摘要
借助顺磁性离子（Pr-3+）作为位移试剂，对超声处理的磷脂分散体的13-C NMR光谱进行了研究。该方法能够区分囊泡膜的外表面和内表面，并且比1-H NMR给出更多种类的信号。已发现镧系元素诱导位移取决于存在的其他离子以及膜的脂质组成。
