Abstract
A new estimate of diamagnetic anisotropy of the frog rhodopsin is reported. The estimate is obtained by combining the data of magnetic field induced orientation of isolated frog rod outer segments as measured by Chagneux and Chalazonitis (1972) and the data of diamagnetic anisotropy of lecithin membranes as recently reported by Boroske and Helfrich (1978). The anisotropy of the volume susceptibilities of frog rhodopsin is calculated to be 4.4 X 10(-8) cgs unit/cm3, which corresponds to 1.5 X 10(-27) cgs unit/molecule, or 9.0 X 10(-4) cgs unit/mol.
摘要
本文报道了对青蛙视紫红质抗磁各向异性的新估计。该估计值是通过结合沙涅和查拉佐尼蒂斯（1972年）测量的孤立青蛙视杆外段磁场诱导取向的数据以及博罗斯克和赫尔弗里希（1978年）最近报道的卵磷脂膜抗磁各向异性的数据而获得的。青蛙视紫红质体积磁化率的各向异性经计算为4.4×10^(-8) 厘米克秒制单位/立方厘米，相当于1.5×10^(-27) 厘米克秒制单位/分子，或9.0×(10^(-4)) 厘米克秒制单位/摩尔。
