Abbreviations used Gal-l-P, galactose-l-phosphate UDPG, uridine diphosphate glucose G-l-P, glucose-l-phosphate G-6-P, glucose-6-phosphate F-6-P, fructose-6-phosphate F-l,6-P, fructose-1,6-diphosphate G-3-P, glyceraldehyde-3-phosphate DHAP, dihydroxyacetone phosphate F-l-P, fructose-1-phosphate PG, 6-phospho-gluconic acid R-5-P, ribulose-5-phosphate S-7-P, sedoheptulose-7-phosphate. 

UDPG was the first of a whole new class of nucleotides, in which the uridine diphosphate group is attached to a monosaccharide. Two important members of the class are uridine diphosphate glucuronic acid, the intermediate in the synthesis of glucuronides and of many other compounds, and uridine diphosphate N-acetylglucosamine which is an intermediate in the synthesis of mucopolysaccharides. Uridine diphosphate muramic acid was isolated by Park (P2) from Staphylococcus aureus...

In a synthesis of coenzyme uridine-diphosphate-glucose (UDPG), Todd and coworkers protected the primary 5-hydroxyl group of uridine (5) by tritylation, benzylated the 2- and 3-hydroxyl groups (6), and removed the trityl group with 80% acetic acid.
