Used in biochemical research for enzyme assays involving glycosyltransferases, particularly in the study of carbohydrate metabolism. Serves as a substrate in the synthesis of glycoconjugates such as glycoproteins and glycolipids. Employed in cell-free systems to investigate nucleotide sugar transport and utilization. Also utilized in studies of UDP-glucose formation and in the development of diagnostic kits for metabolic disorders. Its disodium salt form enhances solubility and stability in aqueous solutions, making it suitable for in vitro applications.
