Bilirubin diglucuronide’s water solubility allows it to be secreted with other bile components into the small intestine where it is converted to urobilinogen. The faith of urobilinogen is to either be transported to the kidneys after being reabsorbed into the bloodstream, or to remain in the intestine and be converted to stercobilin. Urobilinogen is converted to urobilin in the kidneys, and is then excreted with urine giving it its yellow color. Stercobilin is excreted with feces and is responsible for its red-brown color.
