Cholesterol and phosphatidylcholine uptake from dipalmitoyl-phosphatidylcholine liposomes by rabbit spermatozoa showed a complex dependence on temperature in these experiments. At 5 degrees and 20 degrees C, the rate of lipid uptake correlated with temperature. However, from 20 degrees to 37 degrees C uptake did not evidently increased. The results in interpreted as evidence of a thermotropic transition in the sperm plasma membrane. Data are presented showing incorporation of these lipids, especially that of cholesterol, into sperm plasma membrane.
在这些实验中，兔精子从二棕榈酰磷脂酰胆碱脂质体摄取胆固醇和磷脂酰胆碱的过程表现出对温度的复杂依赖性。在5摄氏度和20摄氏度时，脂质摄取速率与温度相关。然而，从20摄氏度到37摄氏度，摄取量并未明显增加。这些结果被解释为精子质膜发生热致转变的证据。文中给出的数据显示了这些脂质，尤其是胆固醇，掺入精子质膜的情况。
