Figure 2
Phases formed by monoolein as a function of temperature and hydration. At the centre of the figure is the corresponding temperature–composition phase diagram. Arrayed around it are cartoon representations of the solid (Lc), liquid (FI) and liquid crystalline [cubic 1 (Pn3m), cubic 2 (Ia3d), HII, Lα) phases, where coloured zones correspond to water layers or channels. The phase diagram was generated in the heating and cooling directions from 20°C. Liquid crystalline phases below ∼17°C are in an undercooled thermodynamically unstable state.
