Several studies have explored structural changes in dehydrating membranes using, e.g., small-angle X-ray scattering (SAXS) and solid-state nuclear magnetic resonance with magic angle spinning (MAS ssNMR) experiments, as well as molecular dynamics (MD) simulations. MD simulations are unique among the listed techniques in that they allow visualizing membrane behavior on atomic level: Membranes under biologically relevant conditions are fluids, and possess only shortrange molecular order. However, the reliability of MD simulations depends heavily on their verifiability against experiments sensitive to atomic-scale structure. The MD model (force field) used to describe the geometries and energies of molecules needs to veritably depict the structure and dynamics of the biomembrane under the simulated conditions.
