The molecule is an organophosphate oxoanion obtained by deprotonation of the phosphate and diphosphate functions of 4-O-[1-D-ribitylphosphonato-(2R)-1-glycerylphosphonato]-N-acetyl-beta-D-mannosaminyl-(1->4)-N-acetyl-alpha-D-glucosaminyl ditrans,octacis-undecaprenyl diphosphate; major species at pH 7.3. It is a conjugate base of a 4-O-[1-D-ribitylphosphono-(2R)-1-glycerylphosphono]-N-acetyl-beta-D-mannosaminyl-(1->4)-N-acetyl-alpha-D-glucosaminyl ditrans,octacis-undecaprenyl diphosphate.
