Figure 5 :DSC curves of MLV liposomes made of pure DMPC or containing increasing molar fractions (Xo = 0-0.15) of a model host compound. (a), a compound exhibiting a reduced interaction with the PL bilayers (e.g., a polar molecule) induced limited thermotropic effects; (b) strong deformation of the DSC curves of PL bilayers under the influence of a lipophilic compound (F.
