The molecule is a polyprenyl phospho oligosaccharide where 6-O-(1-glycerylphospho)-N-acetyl-beta-D-mannosaminyl-(1->4)-N-acetyl-beta-D-glucosaminyl comprises the oligosaccharide component and the polyprenyl chain consists of eleven prenyl units. It is a conjugate acid of a 6-O-(1-glycerylphosphonato)-N-acetyl-beta-D-mannosaminyl-(1->4)-N-acetyl-beta-D-glucosaminyl undecaprenyl diphosphate(3-).
