Abstract

In a magnetic field of up to 7 kG, myelin figures of the egg-yolk phosphatidylcholine/water system were oriented because of the diamagnetic anisotropy of the molecules through bending at the roots with the long axes parallel to the field. The time interval for an angular change of their axes was nearly in proportion to H-2. From the orientational behaviour, a curvature-elastic modulus K of lipid-bilayer could be roughly evaluated as 4 X 10(-13) erg.

摘要

在高达7千高斯的磁场中,蛋黄磷脂酰胆碱/水体系的髓鞘样结构因分子的抗磁各向异性而发生取向,其长轴在根部弯曲并与磁场平行。它们轴的角度变化的时间间隔几乎与H-2成正比。根据取向行为,脂质双层的曲率弹性模量K可粗略估计为4×10^(-13)尔格。
