The molecule is a lipid A derivative in which an alpha-Neu5Ac-(2->3)-beta-D-Gal-(1->3)-beta-D-GalNAc-(1->4)-[alpha-Neu5Ac-(2->3)]-beta-D-Gal-(1->3)-L-alpha-D-Hep-(1->3)-[beta-D-Glc-(1->4)]-L-alpha-D-Hep6PEtn branched decasaccharide is linked (1->5) to a lipid A component containing four C14 and two C16 fatty acyl chains. Reported as a proposed lipooligosaccharide outer core structure of Campylobacter jejuni strains (CO016 and GC105) isolated from patients with Guillain-Barre syndrome (GBS) who had anti-GM1b antibodies, but neither anti-GM1 nor anti-GD1a antibodies (PMID:25867522).
