Abstract

We present random walk models for the diffusive motion of lipid probe molecules in a lipid bilayer and calculate the diffusion constants for probes spanning the entire bilayer and for probes extending through one lipid layer only. The "stiffness" of such molecules can explain the observed value of 2/3 for the ratio of these diffusion constants.
