WebDSC profiles of biological membranes revealed not only endothermic peaks related to the melting process of complex mixtures of lipids (as in Fig. 2.17) but also broad endothermic peaks occurring at higher temperatures than the lipid melting events. These peaks correspond to the denaturation process of more ordered structures than the lipids.
