Schematic architecture of the simulated phospholipid bilayer system. (a) Monomolecular structure of DMPC. The red ball represents the C₂₁ atom of a DMPC molecule, which is applied for labeling the location of the entire molecule. (b) Top view of the bilayer consisting of 512 DMPC molecules, 256 molecules per layer. (c) Side view of the simulated system, including the DMPC-containing bilayer, Na⁺ (blue balls), Cl⁻ (yellow balls), and water (light blue).
