Non-enzymatic/bacterial oxidation to stercobilin/urobilin
What it does, reaction by reaction
Heme Degradation (Bilirubin Pathway) Amino Acid & Nitrogen Metabolism · Reticuloendothelial system, liver ER, gut
Urobilinogen → stercobilin (feces) or urobilin (urine)
Converts Urobilinogen into Stercobilin (feces) or urobilin
› Notes
Most urobilinogen is oxidized in the intestine to brown stercobilin and excreted in feces; a portion is reabsorbed through portal blood, and a small fraction escapes hepatic uptake and is oxidized to yellow urobilin in urine. Enterohepatic cycling returns much of the absorbed urobilinogen to bile.
