Figure 5

Snapshots from molecular simulations illustrating the formation of TG- and CE-rich clusters to the air side of the interface at high surface pressures (small areas per lipid). (A–C) Lipid layer illustrated from the air phase with an area per lipid of (A) 64 Å2, (B) 53.1 Å2, and (C) 42.1 Å2. POPC headgroups are shown in orange, TG in pink mesh, CE in green, and FFA (palmitate) in red. (D–F) Lipid layer depicted from the side, the water phase being below the layer. The area per lipid is (D) 64 Å2, (E) 53.1 Å2, and (F) 42.1 Å2. POPC headgroups are shown in orange, TG in blue, CE in green, FFA (palmitate) in red, and water in gray mesh. In all plots for POPC, only the headgroup choline is shown; for other molecules, the coloring is for the whole molecule.
