title: [Phase transitions, lipid-lipid interactions and their role in some biostructures].
abstract: The phase states and phase transitions of some lipids, lipid mixtures of blood and tissues of some animals and human were examined by the method of scanning calorimetry (DSC-2, "Perkin--Elmer"). It was determined that in monohydrated and in hydrated systems, cholesterol produces a liquefying effect on the total phospholipids of the brain and blood. In complex multicomponent lipid systems changes of the phase states and of temperatures of the phase transitions of some lipids were discovered. The role of these phase transitions and miscibility of lipids for functioning of the cellular membranes and of the key-enzymes in the process of changes of lipoproteins of the blood (LCAT) is being discussed, as well as the connection of the phase transitions of cholesterol esters of the blood with atherosclerosis.
