[Structural transitions associated with changes in the thickness and density of phospholipid bilayers]. / Strukturnye perekhody, soprovozhdaiushchiesia izmeneniem tolshchiny i plotnosti fosfolipidnogo bisloia.

Relationship between a change of bilayer density and thickness and dissociation degree of the polar groups of phospholipid molecules was studied. It has been stated that with a decrease of ionization level a transition of bilayer from liquid to ordered state should occur. The latter is accompanied by a decrease of thickness and increase of density of the bilayer.
