Název v původním jazyce

Stability of the inverted hexagonal phase

Popis výsledku v původním jazyce

The inverted hexagonal phase (HII) belongs to the biologically most significant nonlamellar lipid phases in biomembranes. Hence the geometric properties and conditions of transition to the HII phase are nowadays widely studied. In this chapter we offer abrief overview on the mechanics of the HII lipid phase. In our derivation of the free energy of lipid monolayers, we assume that lipid mole- cules are in general anisotropic with respect to the axis perpendicular to the membrane plane. In our model theexpression for the lipid monolayer free energy consists of two energy contributions: the bending energy which involves also a deviatoric term, and the interstitial energy which describes the deforma- tion energy due to stretching of the phospholipid molecule chains. On the basis of the derived expression for the lipid monolayer free energy, we theoretically predict optimal geometry and physical conditions for the stability of the inverted hexagonal phase.
