用差示扫描量热法和X射线衍射法研究了饱和链磷脂的结构。磷脂酰乙醇胺和磷脂酸在高温下都可以形成六方相。向六方相转变的温度与链长和钠盐浓度有关。随着链长的增加或钠盐浓度的增加，转变温度降低。除了高温下的这种转变外，在一些磷脂中还检测到低温下的量热转变。
The structure of phospholipids with saturated chains was investigated by differential scanning calorimetry and by X-ray diffraction. Both phosphatidylethanolamines and phosphatidic acids can exhibit a hexagonal phase at high temperature. The temperature of the transition to the hexagonal phase is dependent on chain length and sodium salt concentration. Increasing the chain length or the sodium salt concentration results in a decrease in the transition temperature. In addition to this transition at high temperature, a calorimetric transition at low temperature is detected in some phospholipids.
