Lipid Membrane Structure and Dynamics Studied by All-Atom Molecular Dynamics Simulations of Hydrated Phospholipid Bilayers

Abstract

Abstract The structure and dynamics of phosphatidylcholine bilayers are examined by reviewing the results of several nanoseconds of molecular dynamics simulations on a number of bilayer and monolayer models. The lengths of these simulations, the longest single one of which was 2 nanoseconds, were sufficiently long to effectively sample many of the longer-scale motions governing the behaviour of biomembranes. These simulations reproduce many experimental observables well and provide a degree of resolution currently unavailable experimentally.
