Abstract
In a differential scanning calorimetry and X-ray study 12 different lipid-water model systems have been investigated in the temperature region from 250 to 290 K. Structural changes of the lipid system are observed in most cases in the course of freezing or melting of excess water, although the structures of the phases existing around 273 K were quite different. According to thermodynamic considerations a concentration jump (lyotropic stress) is predicted in all cases during the freezing process of excess water. The given lipid-water system reacts to the lyotropic stress in a specific way according to its individual phase diagram.Keywords
