ABSTRACT
We use a long, all-atom molecular-dynamics (MD) simulation combined with theoretical modeling to investigate the dynamics of selected lipid atoms and lipid molecules in a hydrated diyristoyl-phosphatidylcholine lipid bilayer. From the analysis of a 0.1 micros MD trajectory, we find that the time evolution of the mean-square displacement, <[deltar(t)]2>, of lipid atoms and molecules exhibits three well-separated dynamical regions (i) ballistic, with <[deltar(t)]2> approximately t2 for t
