FIG. 1

Ion distributions around the charged DOPG bilayer. (a) A snapshot of the 32Cl system at 79 ns of the MD simulations. Lipids are displayed with carbonyl and hydroxyl groups highlighted with thick bonds and phosphorus atoms as gold spheres. Adsorbed and diffuse Na+ ions are displayed as blue and cyan spheres, respectively, and Cl− are displayed as red spheres. The lower leaflet is only partially shown. (b) A close-up view of the interactions around a Na+ ion penetrated into the bilayer Favorable interactions with three carbonyls and two hydroxyls are indicated by dotted lines.
