FIGURE 7.
A series of snapshots of water penetration for the same result as that shown in Fig. 3. Water molecules are signified by blue spots, and acyl chains are eliminated. (a) Equilibrium state; (b) 0.15 ps. Some water molecules were carried into the hydrophobic region; (c) 0.30 ps; (d) 0.45 ps. Even in the rebound stage, water molecules still penetrated into the hydrophobic region.
