diacylglycerophosphocholines containing various octadecynoic acids (4-, 6-, 9-, 12-, 14- and 17-octadecynoic acid) were synthesized and purified to homogeneity. Their behaviour in monolayers, when studied by the Langmuir-Blodgett film balance technique, revealed systematic relationships between structure and packing properties. The thermotropic phase behaviour of these novel phospholipids, as measured by
合成了含有各种十八碳烯酸(4-,6-,9-,12-,14-和17-十八碳烯酸)的异构二酰基甘油磷酸胆碱,并纯化至均质。当通过Langmuir-Blodgett膜平衡技术研究时,它们在单层中的行为揭示了结构与填充性能之间的系统关系。通过差示扫描量热法测量,这些新型磷脂的热致相行为系统性地取决于三键的位置:凝胶-液晶相变温度(Tm)至少通过-3.4 C表示位置9的三键。
