The molecule is a polyprenyl phospho oligosaccharide where alpha-D-FucNAc4-(1->4)-beta-D-ManNAcA-(1->4)-D-GlcNAc comprises the oligosaccharide component and is linked via a diphosphate to a polyprenyl chain consisting of eleven prenyl units. It is a conjugate acid of an alpha-D-FucNAc4-(1->4)-beta-D-ManNAcA-(1->4)-D-GlcNAc-undecaprenyl diphosphate(3-).
