Abstract

The magnetic anisotropy of a polymembrane cell, such as the external segment of the frog retinal rod, is defined as the difference between the axial magnetic susceptibility (chiar), chia - chir = deltachi of the segment. After the total photolysis of the rhodopsin in situ, deltachi decreases a significantly by 20%. This decrease in magnetic anisotrophy should involve a subtle molecular disorder, mostly due to an alteration of the rhodopsin molecule.

摘要

多膜细胞（如蛙视网膜视杆细胞的外段）的磁各向异性定义为该段轴向磁化率（χ||）与横向磁化率（χ⊥）之差，即χ|| - χ⊥ = Δχ。视紫红质在原位完全光解后，Δχ显著下降20%。磁各向异性的这种下降应涉及一种细微的分子无序状态，这主要是由于视紫红质分子的改变所致。
