Carbothdrate Nanotubes

Abstract

Assembly of units in an alternating disrotatory fashion is a feature of the solid-state structure of an achiral, synthetic cyclic decasaccharide composed of ten α-(1→4)-linked, alternating D- and L-rhamnopyranose residues. The unit cell contains two crystallographically independent, Ci-symmetrical, cylindrical molecules. This gives rise to parallel nanotubular arrays with internal diameters of about 13 nm as depicted on the right.
