Pigment produced by the destruction of hemoglobin in the liver is called?
When the erythrocytes are destroyed, haemoglobin breaks down,
the heme part of it goes through a series of transformation:
Heme → biliverdin (green pigment)
biliverdin → bilirubin (orange-yellow pigment)
Bilirubin + blood albumin → bound bilirubin (in peripheral
blood)
Bound bilirubin + glucuronic acid → conjugated bilirubin. (in
liver)
Conjugated bilirubin + intestinal bacteria → several pigments,
including
- stercobolin (orange-brown pigment, excreted in feces) and
- urobilinogen (reabsorbed into bile/blood, finally excreted in
urine)
