title: [Use of bromthymol blue for studying the thermotropic properties of the liposomes from egg lecithin].
abstract: The dependence of the turbidity changes at 615 nm monobilayers liposomes from egg yolk lecithin in the presence of bromothymol blue on temperature and storage conditions has been investigated. It is established that the thermotropic properties of liposomes change irregularly and depend on the storage conditions. Sharp release of the bound dye at temperature above 35-37 degrees C is associated with thermotropic change in liposomes and the detected effects, with the change of orientation of the phosphorylcholine group.
