Acetone in Water: Pre-Equilibration • Pre-‐equilibra4on of the system using classical MD • Program: SANDER – Simulated Annealing with NMR-‐Derived Energy Restraints – Energy minimiza4on, molecular dynamics, NMR refinements, ... – Long-‐range interac4ons • electrosta4c: par4cle-‐mesh Ewald procedure (op4onally „true“ Ewald sum) • van-‐der-‐Waals: es4mated by a con4nuum model – Users can define restraints on bonds, angles, and torsions
