The molecule is an amino pentasaccharide consisting of a di-N-acetylated lactosediamine to which is linked (1->3) an alpha-L-fucosyl residue and which is in turn linked (1->3) to the galectose residue of a second lactose moiety. Saccharide portion of the antigen lacdiNAc fucopentaose-BSA. It is an amino pentasaccharide and a glucosamine oligosaccharide.
