General description

Uridine 5′-diphosphoglucuronic acid (UDPGA) is a cofactor, synthesized from UDPglucose and nicotinamide adenine dinucleotide (NAD+) intracellularly by the catalytic activity of UDPglucose dehydrogenase. The concentration of UDPGA in a number of liver preparations ranges from 0.3-0.5 mM.


Uridine 5′-diphosphoglucuronic acid ammonium salt has been used in the initiation of UDP-glucuronosyl transferase (UDGPT) assay towards 14C-testosterone in the liver S9 protein. It is suitable for use in UDGPT assay.

After being incubated with animal and human liver microsomes, metabolites of phase I and II were investigated. A comparison was performed by ultrahigh performance liquid chromatography-quadrupole/time-of-flight coupled to mass spectrometry (UHPLC-Q/TOF). Consequently, a total of four phase I metabolites and


Glycosyltransferases: Tools for Synthesis and Modification of Glycans

The presence of multiple functional groups and stereocenters in complex carbohydrates makes them challenging targets for the organic chemist.


Glycosyltransferases were initially considered to be specific for a single glycosyl donor and acceptor, which led to the one enzyme-one linkage concept. Subsequent observations have refuted the theory of absolute enzymatic specificity by describing the transfer of analogs of some nucleoside mono- or diphosphate sugar donors.
