描述
Bilirubin diglucuronide is a water soluble version of bilirubin. Conversion of bilirubin IX-alpha to a water-soluble form by disruption of the hydrogen bonds is essential for elimination by the liver and kidney. This is achieved by glucuronic acid conjugation of the propionic acid side chains of bilirubin. Bilirubin glucuronides are water-soluble and are readily excreted in bile. Bilirubin is primarily excreted in normal human bile as diglucuronide; unconjugated bilirubin accounts for only 1-4% of pigments in normal bile. [HMDB]
