Figure 5.

Equilibrium L_o and L_d phases become purer with increasing hydrophobic tail length mismatch (3:0 PC, 4:0 PC, and 5:0 PC saturated lipids). The bulk compositions are measured as for Figure 4, outlined in the Methods. (A) Representative snapshots at t = 9.75 μs for each mixture (compare those in Figure 2). (B) The compositions of the phases are identified as in Figure 4 and averaged over the final 0.5 μs, and points for the three separate simulations of each mixture plotted on Gibbs triangles. The overall composition is shown as a black cross.
