Lipids aren't polymers like proteins, so you'll have to create a special
topology or
rtp entry for every sort of lipid. Some of them are already present in
the forcefield
files, but most people simulating lipids prefer to use specially tuned
force fields
(check the literature), since the normal ones are usually tailored for
