What is a true statement regarding urobilinogen?

The statement that urobilinogen is formed in the intestines by bacterial reduction of bilirubin is accurate. When bilirubin is produced from the breakdown of hemoglobin, it is transported to the liver, where it gets conjugated and then secreted into the bile. Once the bile reaches the intestines, intestinal bacteria metabolize the conjugated bilirubin to produce urobilinogen. This compound can be reabsorbed into the bloodstream, some of which is eventually excreted in urine, while the remaining is converted to stercobilin, giving feces their characteristic brown color. This process highlights the important role of gut bacteria in transforming bilirubin into urobilinogen, making the statement true.
