The MARTINI Force Field: Coarse Grained Model for Biomolecular Simulations.

@article{citeulike:1406542, abstract = {We present an improved and extended version of our coarse grained lipid model. The new version, coined the MARTINI force field, is parametrized in a systematic way, based on the reproduction of partitioning free energies between polar and apolar phases of a large number of chemical compounds.
