The molecule is the organophosphate oxoanion that at pH 7.3 is the major microspecies present of undecaprenyldiphospho-N-acetyl-(N-acetylglucosaminyl)muramoyl-L-alanyl-D-isoglutaminyl-(glycyl)3-L-lysyl-D-alanyl-D-alanine, formed by loss of two protons from the diphospho group. It is a conjugate base of an undecaprenyldiphospho-N-acetyl-(N-acetylglucosaminyl)muramoyl-L-alanyl-D-isoglutaminyl-(glycyl)3-L-lysyl-D-alanyl-D-alanine.
