The visualizations showed areas with disordered lipid tails for the single bilayer MMG-6 system, which indicates that the system displays properties resembling those of the ripple phase. Based on the visual observation alone, the acyl chains are aligned parallel to the lipid bilayer normal in the interdigitated systems, and this type of tail packing also remains in the non-interdigitated systems containing MMG-1. The non-interdigitated MMG-6 systems (single bilayer, double bilayer) display different tail tilts and slightly thinner membrane structures, which are visible, especially when the systems are viewed from the side (Figure ). Some degree of partial interdigitation with accompanying membrane deformations was observed for all systems with non-interdigitated starting configurations.
