This investigation presents a quantitative analysis of the asymmetric transmembrane lipid packing geometry in egg phosphatidylcholine vesicles. The analysis uses hydrodynamic and nuclear magnetic resonance data obtained for homogeneous egg phosphatidylcholine vesicles and demonstrates that the average area per lipid head group and effective length of the lipid are greater on the outer monolayer than on the inner monolayer of the egg phosphatidylcholine vesicle. Results also indicate that the bilayer of the egg phosphatidylcholine vesicles has an asymmetrical interface through its center.
本研究对卵磷脂酰胆碱囊泡中不对称跨膜脂质堆积几何结构进行了定量分析。该分析使用了从均匀的卵磷脂酰胆碱囊泡获得的流体动力学和核磁共振数据,并表明卵磷脂酰胆碱囊泡外层单分子层上每个脂质头部基团的平均面积和脂质的有效长度大于内层单分子层。结果还表明,卵磷脂酰胆碱囊泡的双层膜在其中心具有不对称界面。
