Coarse-Grained Molecular Dynamics Problem of Scale . One of the main unresolved problems in biological science is the time-scale and length-scale gap between computational and experimental methods of studying biological systems. Chemical and mechanical processes on an atomic level form the basis of all phenomena in living systems. This model differs from other coarse grained protein models due to the introduction of a novel angle Transmembrane proteins can function on both sides of the membrane or transport molecules Khalid S, Sansom MSP.
