Uridine diphosphate glucuronic acid ammonium  (Synonyms: UDP-α-D-glucuronic acid ammonium)

Uridine diphosphate glucuronic acid ammonium (UDP-α-D-glucuronic acid ammonium) is a glucuronic acid donor. Uridine diphosphate glucuronic acid ammonium transfers its glucuronic acid moiety to acceptor molecules, thereby forming "ether" glucuronides, while being converted into uridine 5'-pyrophosphate. Uridine diphosphate glucuronic acid ammonium serves as a substrate for Arabidopsis UDP-GlcA 4-epimerase 1, and undergoes reversible 4-epimerization to generate UDP-α-D-galacturonic acid^[1][2].

Uridine diphosphate glucuronic acid (1 mM; 30 min) ammonium acts as the active substrate for recombinant truncated Arabidopsis AtUGlcAE1Δ1-64^[2].
