The main features of the primary structure of the octasaccharide, α-D-Glcp-(1-2)-α-D-Glcp-(1-2)-[α-D-GalpNAc-(1-3)]-α-D-Galp-(1-3)-α-D-Glcp-(1-3)-[α-LD-Hepp-(1-7)]-α-LD-Hepp-(1-3)-α-LD-Hep, have been determined in the ab initio manner by 1H-n.m.r. spectroscopy without resorting to biochemical methods of analysis. Several nontypical interresidue n.O.e. values point to a preferred solution conformation of the molecule.
