Phase diagrams of DOPC/DPPC-d62/Chol. (a) A constant temperature cut through the ternary phase diagram at 10°C shows phase assignments. The liquid–liquid (Ld-Lo) coexistence region is shaded blue and terminates in a critical point at the yellow circle. At low cholesterol, the Ld-Lo region is bounded by a three-phase triangle shaded green, in which Ld, Lo, and So phases coexist. The three-phase triangle is connected to two separate regions of solid–liquid coexistence (Lo-So and Ld-So), which are shaded red. (b) Multiple constant-temperature phase diagrams are assembled into a three-dimensional ternary phase diagram spanning 10°C and 37°C, with the dashed yellow line approximating a line of critical points.
