Abstract

Ethylene di-11-bromoundecanoate, C24H44Br2O4, was synthesized as a model for the hydrophobic moiety of saturated phospholipids. The crystals are monoclinic, space group P21/a, with two molecules per unit cell. Unlike folded configurations proposed for phospholipids in biological membranes, the hydrocarbon chains of this diester are fully extended in the crystalline state.
