Abstract
The use of (2)H NMR spectral moments to determine the composition of biphasic lipid mixtures is outlined. The analysis has been applied to phosphatidylethanolamine-cholesterol (1:1), potassium palmitate, 30% (wt/wt) water and phosphatidylcholine-cholesterol (4:1) systems, as well as to membrances of Escherichia coli during phase transitions. The advantages and disadvantages of the use of spectral moments to determine fractions of coexistent phases are discussed.
摘要
概述了利用（2）H核磁共振谱矩来确定双相脂质混合物的组成。该分析已应用于磷脂酰乙醇胺 - 胆固醇（1:1）、棕榈酸钾、30%（重量/重量）水和磷脂酰胆碱 - 胆固醇（4:1）体系，以及大肠杆菌膜在相变过程中的情况。讨论了使用谱矩来确定共存相分数的优缺点。
