✦ Synopsis

A model is proposed for hydrocarbon chain dynamics in lipid bilayers. In the upper and middle parts of the chain all motion occurs by concerted rotations around at least two carboncarbon bonds at a time, preserving a structure with kinks (that is gauche + trans gauche ~ conformations) as the only deviations from the all-trans chain. At the end, independent rotations around carbon-carbon bonds play a larger and larger part. This gives a reasonable interpretation of deuterium NMR data.

## ¨¨Ä bstract The main features of a subcell catalogue for the packing of molecules with long alkyl chains were developed in the period of 1950᎐1975 based on single crystal studies. In the last number of years many deviations from these typical packing modes in a subcell lattice were found and an

The role of repulsive forces in the nonlinear dynamics of lipid bilayers is described, using a hydrodynamic approach. The lipid bilayer is considered as a fluid film with tangentially immobile surfaces and a general order parameter profile is assessed, depending on the degree of orientation of the h
