Summary of simulated trajectory analyses for DMPC and DMPC/C16; total bilayer area (in the XY plane), area per lipid, bilayer width (along Z-axis), and numbers of hydrogen-bonds. Note that a DMPC molecule has 9 potential hydrogen-bond acceptors and no donors. C16-ceramide has 3 potential donors and 4 potential acceptors (Fig. 4a).
