Initially, we tried to simulate the interaction of gel-phase DLPE membranes at room temperature and A=42 Å. It turned out, however, that the force field used failed to reproduce the gel state of the membranes, resulting in a substantially disordered structure corresponding rather to the liquid-crystalline state.

The use of a statistical ensemble with a fixed lateral area of the simulation cell and a fixed number of lipid molecules could, in principle, partially suppress fluctuations in the local areal density of the lipid, which could affect the membrane permeability. For a simulation cell containing 32 symmetrically independent lipid molecules per monolayer, as in our case, the use of a fixed membrane area ensemble should however have little effect on the fluctuations in the local areal density. This follows from the MD results reported by S. E. Feller and R. W. Pastor, [J. Chem. Phys. 111, 1281 (2005]) who compared the probability distributions of single molecule areas in fixed- and variable-area ensembles for a hydrated lipid membrane with 36 independent molecules per monolayer in the simulation cell.

Throughout the article, the atom numbering is as suggested by Sundaralingam [Ann. N.Y. Acad. Sci. 195, 324 (1972)]. The two carbon atoms in parentheses belong to the glycerol residue.

We here imply a large separation range, where the oscillations of water density and hydration pressure can be neglected.
