The molecule is a branched hexasaccharide derivative consisting of a linear tetrasaccharide unit of beta-L-rhamnose, beta-D-glucose, and two alpha-L-rhamnose residues, linked sequentially (1->4), (1->3) and (1->3), to the non-reducing-end alpha-L-rhamnose residue is also linked (1->2) an alpha-D-glucuronosyl-(1->6)-alpha-D-glucosyl disaccharide branch, the whole linked glycosidically to a 5-aminopentyl group. It is a hexasaccharide derivative and a glycoside.
