Description 143-154
Using
planar lipid membrane as the model for
biological membranes, we have studied the role of lipid medium in the mechanism
of transmembrane charge transport. Here we present a
review of our results which indicate that (a) both electrons and
ions are charge carriers across these membranes, (b) hydrophilic pores are formed
in the planar lipid membrane ", providing the required
ionic pathways, (c) membrane I-V characteristics are nonlinear and are
monitored by the presence of external agents in the bathing solution,
temperature and frequency of the applied electric field. We show
that these observations can be explained in the light of semiconducting nature
of lipid molecules, double electrode behaviour of the membrane and the theory
of charge conduction in binary, inhomogeneous, disordered systems.
