| 摘 要： | 本文报导采用小角X射线散射方法(SAXS)对甲醇、乙醇和异丁醇分别与含水卵磷脂所形成的液晶相结构的研究. 它们与水-卵磷脂形成的液品结构有较大区别. 在水-卵磷脂体系中, 随着含水量增加, 双分子层层间距增大. 但当醇类加入水-卵磷脂体系中, 随着醇类含量增加, 层间距变小, 随着醇类中碳链的增长, 支链的引入, 层间距变小趋势强化。

| Abstract: | Liquid-crystal system consists of egg yolk phospho-liqid (PC) and little water was studied by means of the small angle X-ray scatter (SAXS), in methanol, ethanol or isobutynol. Experments show thet layer distance decreases as the alcohol content increases in the system studied (5% H_2O-PC-alcohol) and as the hydrocarbon chain or branched chain increased in these alcohols, the layer distance is decreased. We consider that these changes might be in consequnce of the changes of molecule or force in the system. For this reason, it might be plausible that drinking a lot of alcohol would distroy the structure of biological liquid-crystal in the humanb boby and make human boby poisoning. |
