UDP-Glucuronic acid is a nucleoside diphosphate sugar that is a source of glucuronic acid for polysaccharide biosynthesis. This compound can be used for the formation of many glucuronides with various aglycones.1 1.Green, M.D., and Tephly, T.R.Glucuronidation of amine substrates by purified and expressed UDP-glucuronosyltransferase proteinsDrug Metab.

UDP-N-acetyl-D-Glucosamine is a natural nucleotide sugar that is used by glycosyltransferases to transfer N-acetyl-D-glucosamine residues to substrates.1It is an important component of antibiotic biosynthesis pathways in fungi and lipopolysaccharide production in bacteria.2,3 1.Roseman, S.Reflections on glycobiologyJ.
