The molecule is a nucleotide-sugar oxoanion that is the conjugate base of UDP-2-acetamido-4-amino-2,4,6-trideoxy-D-glucose arising from deprotonation of the phosphate OH groups and protonation of the 4-amino group; major species at pH 7.3. It is a conjugate base of an UDP-2-acetamido-4-amino-2,4,6-trideoxy-D-glucose.
