The structure of phospholipids with saturated chains was investigated by differential scanning calorimetry and by X-ray diffraction. It is shown that 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, a calorimetric transition at low temperature is detected in some phospholipids.
通过差示扫描量热法和X射线衍射研究了具有饱和链的磷脂结构。结果表明，磷脂酰乙醇胺和磷脂酸在高温下都能呈现六方相。向六方相转变的温度取决于链长和钠盐浓度。链长或钠盐浓度增加会导致转变温度降低。除了这种高温转变外，在一些磷脂中还检测到低温下的量热转变。
