What collective term encompasses the reduction products stercobilinogen, urobilinogen, and mesobilirubinogen?

Explanation:
When bilirubin is processed in the gut by bacterial action, it is reduced to several colorless products that together form a group called urobilinogens. Among these are stercobilinogen, urobilinogen, and mesobilirubinogen. These reduced pigments can then be further oxidized to colored compounds such as urobilin (in urine) and stercobilin (in feces). So the term that encompasses all of these reduction products is urobilinogen, representing the family of related compounds produced in the intestinal bacteria–mediated bilirubin reduction.
