Representative snapshots of atomic-scale MD simulation systems. The simulation model has a PSurf monolayer, into which the VEA molecules originally in the air phase integrate spontaneously. The effect of surface pressure is described by varying the average area per lipid (APL), whereby a small APL corresponds to a high surface pressure (and vice versa). For clarity, only half of the simulation box is depicted. Color coding: VEA (red), PSurf lipids (DPPC, POPC, POPG, Chol) (yellow), and water (blue surface).
