FIGURE 4.

Schematic phase diagram of a SOPC-cholesterol binary mixture as discussed in the text. The lines connecting the points are guides to the eye. The following points were determined from DSC data (♦, onset; ⋄, completion of the phase transition) (43), from proton MAS NMR (▪, onset; □, completion), and from deuterium NMR (•, ○). Phase transition temperatures measured by ²H NMR on sn-1 chain deuterated SOPC were raised by 3°C to compensate for the difference in phase transition temperatures between deuterated and protonated lipids.
