Molecular dynamics simulation trajectories of minimal POPC bilayer (17 lipids per leaflet) at various hydration levels (CHARMM36, 300 K)

Four all-atom MD simulation trajectories of a POPC lipid bilayer at different hydrations: 40, 20, 10, and 5 waters/lipid. 17 POPC (1-palmitoyl-2-oleoyl-sn-glycero-3-phosphocholine) molecules per leaflet. Simulated with GROMACS 2025.4 using the CHARMM36 force field as obtained from CHARMM-GUI on 19.05.2026. Temperature 300 K. Water model CHARMM TIP3P. The uploaded 100 ns trajectories are saved every 10 ps. For equilibration, I recommend skipping skipping 0 ns (40 w/l), 0 ns (20 w/l), 20 ns (10 w/l), and 40 ns (5 w/l), see the included plot of areas-per-lipid over the whole 100 ns.
