Abstract:
A model for the dynamics of quasi-1D lipid structures in biological membranes is proposed. The model takes into account interactions between the lipid heads and hydro-carbon chains, the description of their relaxation dynamics being based on the phenomenological Ginzburg-Landau approach. It is shown that in lateral linear structures of lipids, a soliton-like excitation can propagate with constant velocity. The latter in turn may provide for lateral transport of matter and for membrane conformation changes.
