GROMOS

GROMOS referred to a force field, which is needed for the calculation of molecular dynamics simulations. It was developed at the University of Groningen and the ETH Zurich. On the other GROMOS is the name of a software package for molecular dynamics simulations, which is connected with this force field parameters. The current version is called GROMOS96.

The GROMOS force field, or rather the force fields, because there are different versions, which differ in their parameters, is optimized for the simulation of amino acids and alkanes, but can also be used for proteins or sugars. It is a united atom force field in which some functional groups, that is, those were fused with non-polar hydrogen atoms to form a unit and are considered in the simulation than an atom.
