Abstract	18:0 SM (d18:1/18:0) sphingomyelin A new GROMOS43a1-based force field (43A1-S3) for simulation of membranes with the  Gromacs simulation package. The validity of the force fields is demonstrated by correct replication of X-ray form factors and NMR order parameters over a wide range of membrane compositions in semi-isotropic NTP 1 atm simulations. 43-A1-S3 compares favorably with other force fields used in conjunction with the Gromacs simulation package with respect to the breadth of phenomena that it accurately reproduces.
