It depends on what you want to model; in the illustrated case we want a
liquid crystalline state, not a gel phase.

Again it depends on what you want to model. At 310 K, the DPPC will
become a gel phase. If that's what you want, then go ahead. If it's not,
you'll need to decide the best approach based on the phase transition
temperature and how well the given force field models the phase transition.
