Abstract

The order----disorder thermal transition in porcine low density lipoprotein-1 (LDL1) and low density lipoprotein-2 (LDL2) has been studied by differential scanning calorimetry (DSC), 1H-NMR and ESR spin probing. The results by different methods are in general agreement in that the thermal transition in LDL1 takes place at about 32 degrees C. For LDL2 there are two overlapping transition regions, one centered at about 25.5 degrees C and the other at about 33 degrees C. The nature of the two transitions in LDL2 has been discussed.

摘要

已通过差示扫描量热法（DSC）、1H-NMR和ESR自旋探针研究了猪低密度脂蛋白-1（LDL1）和低密度脂蛋白-2（LDL2）中的有序-无序热转变。不同方法得到的结果总体上是一致的，即LDL1中的热转变发生在约32℃。对于LDL2，有两个重叠的转变区域，一个以约25.5℃为中心，另一个以约33℃为中心。已讨论了LDL2中两个转变的性质。
