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.
