Abstract
We study the anisotropy of the spontaneous curvature induced by a memb rane inclusion consisting of two geminated polymer-lipid molecules. Th e anisotropy is found to be of the order of the mean spontaneous curva ture. Such a strong anisotropy yields a significant reduction of the m embrane bending rigidity K as well as an increase of the saddle splay (K) over bar, which might lead to curvature instabilities.
