The molecule is a branched amino pentadecasaccharide comprising beta-D-galactosyl, beta-D-glucosyl and 2,5-anydro-D-mannose residues linked sequentially (1->4) and (1->6), to the galactosyl residue of which are linked (1->3) two units of beta-D-Gal-(1->4)-beta-D-Glc-(1->6)-[alpha-Neu5Ac-(2->3)-beta-D-Gal-(1->4)]-beta-D-GlcNAc themselves linked (1->3). Obtained by depolymerisation of the group B Streptococcus (GBS) type III capsular polysaccharide during which process the 2,5-anhydro-D-mannose residue is formed from the original reducing-end N-acetyl-glucosaminyl residue (PMID:28439022).
