Metabolite Identification
Common NameHyaluronan
DescriptionEtiocholanolone glucuronide is a natural human metabolite of etiocholanolone generated in the liver by UDP glucuonyltransferase. Etiocholanolone (or 5-isoandrosterone) is a metabolite of testosterone. Classified a ketosteroid, it causes fever, immunostimulation and leukocytosis. Glucuronidation is used to assist in the excretion of toxic substances, drugs or other substances that cannot be used as an energy source. Glucuronic acid is attached via a glycosidic bond to the substance, and the resulting glucuronide, which has a much higher water solubility than the original substance, is eventually excreted by the kidneys.

General function:
Involved in serine-type endopeptidase activity
Specific function:
Cleaves the alpha-chain at multiple sites and the beta- chain between 'Lys-53' and 'Lys-54' but not the gamma-chain of fibrinogen and therefore does not initiate the formation of the fibrin clot and does not cause the fibrinolysis directly. It does not cleave (activate) prothrombin and plasminogen but converts the inactive single chain urinary plasminogen activator (pro- urokinase) to the active two chain form. Activates coagulation factor VII
