Stercobilin is a tetrapyrrolic bile pigment and is one end-product of heme catabolism.[1][2] It is the chemical responsible for the brown color of human feces and was originally isolated from feces in 1932. Stercobilin (and related urobilin) can be used as a marker for biochemical identification of fecal pollution levels in rivers.[3]
