We are using a novel simulation technique which combines traditional Molecular Dynamics under conditions of constant temperature and pressure, and Configurational Bias Monte Carlo. The combined simulation methods provide more efficient sampling of the huge number of configurations of the lipid-cholesterol system. A Fluid Phase Lipid Bilayer Membrane,'' Biophys. Chem B 103, 6323-6327, 1999. P atoms, red are O atoms, and white are H atoms on tne cholesterols.
Sticks are carbon atom bonds.
