The molecule is a polyprenyl glycosyl diphosphate having eleven prenyl units and with 4-O-[di(2R)-1-glycerylphosphono]--N-acetyl-beta-D-mannosaminyl-(1->4)-N-acetyl-alpha-D-glucosamine as the glycosyl fragment. It is a conjugate acid of a 4-O-[di(2R)-1-glycerylphosphonato]-N-acetyl-beta-D-mannosaminyl-(1->4)-N-acetyl-alpha-D-glucosaminyl undecaprenyl diphosphate(4-).
