Figure 4. The effect of adding chemically different lipids to a pure lipid

The effect of adding chemically different lipids to a pure lipid; at left, the melting and crystallization temperatures of a pure lipid are shown—both quite high and with a relatively small difference (i.e., supercooling). By adding a chemically similar but nonidentical second lipid, the melting and crystallization temperatures drop but the second drops more than the first, leading to increased supercooling. Moving to the right, the greater the chemical difference, the greater the amount of supercooling; modified from Reference 8.
