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