Definition

A branched amino decasaccharide comprising a sequence of alpha-sialyl, beta-D-galactosyl, N-acetyl-beta-D-glucosaminyl, beta-D-galactosyl, beta-D-glucosyl and 2,5-anydro-D-mannose residues linked sequentially (2->3), (1->4), (1->3), (1->4) and (1->6), to the N-acetyl-glucosaminyl residue of which is linked also (1->6) an alpha-sialyl-(2->3)-beta-D-galactosyl disaccharide unit, while to the 2,5-anhydro-D-mannose residue at the reducing end is also linked (1->4) a further alpha-sialyl(2->3)-beta-D-galactosyl disaccharide unit. 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 a the original reducing-end N-acetyl-glucosaminyl residue (PMID:28439022).
