I do not know what is the structure of monoolein :((

Then it is strongly possible that OH-C-C-OH is best represented
by the P4 particle type. But it might not be that simple :))

you should once your (first) topology made try it out and compare
to as much data you can find ... experimental and from atomistic
simulations ... that should include dynamics, structure et  
thermodynamics ...

have fun,
XAvier.
