The molecule is a decasaccharide derivative consisting of two N-acetyl-alpha-neuraminyl-(2->3)-beta-D-galactosyl-(1->4)-N-acetyl-beta-D-glucosaminyl-(1->3)-[beta-D-glucosyl-(1->4)]-beta-D-galactose units connected via a beta-(1->4) linkage from the galactose of one unit to the glucose of the other, with a 2-aminoethyl group linked glycosidically to the galactose residue at the reducing end. It is a decasaccharide derivative and a glycoside. It derives from an alpha-Neup5Ac-(2->3)-beta-D-Galp-(1->4)-beta-D-GlcpNAc-(1->3)-[alpha-Neup5Ac-(2->3)-beta-D-Galp-(1->4)-beta-D-GlcpNAc-(1->3)-[beta-D-Glcp-(1->4)]-beta-D-Galp-(1->4)-beta-D-Glcp-(1->4)]-beta-D-Galp.
