The specific volumes of a series of saturated phosphatidylethanolamine dispersions with 12, 14, and 16 carbon atoms per chain have been measured in the region of the chain melting transition, Tm. The change in specific volume at Tm for the 12 and 14 carbon compounds are 0.0160 and 0.0204 mL/g, respectively. Comparisons are drawn between this class of lipids and phosphatidylcholines. In both cases, Tm extrapolates with increasing chain length to the melting point of polyethylene. Both types of lipids appear to be packed in a similar way below Tm. One major difference is that dilaurylphosphatidylethanolamine undergoes a second transition above Tm.
已经在链熔化转变温度Tm区域测量了一系列每条链含有12、14和16个碳原子的饱和磷脂酰乙醇胺分散体的比容。对于含12个和14个碳原子的化合物，在Tm时比容的变化分别为0.0160和0.0204 mL/g。对这类脂质与磷脂酰胆碱进行了比较。在这两种情况下，Tm都随着链长的增加外推至聚乙烯的熔点。在Tm以下，这两种类型的脂质似乎以相似的方式堆积。一个主要区别是二月桂酰磷脂酰乙醇胺在Tm以上会发生第二次转变。
