bile pigments

Last reviewed 01/2018

The bile pigments are a range of substances derived from compounds containing haem e.g.:

  • haemoglobin
  • catalase
  • peroxidase
  • cytochromes
  • myoglobin

They are produced in the liver and excreted in bile. They impart colour to bile - bilirubin and bilverdin - and faeces - urobilin and stercobilin.

Interference with bile pigment excretion can lead to jaundice.
