Ontology: Urobilinogen (C0042052)

Definition (MSH) A colorless compound formed in the intestines by the reduction of bilirubin. Some is excreted in the feces where it is oxidized to urobilin. Some is reabsorbed and re-excreted in the bile as bilirubin. At times, it is re-excreted in the urine, where it may be later oxidized to urobilin.
