The bile pigments, formed by the degradation of haemoglobin.
A green pigment in the bile, produced by oxidation of bilirubin.
The product of the first step in heme catabolism.
Early breakdown product of hemoglobin as part of the normal life-death cycle of red blood cells. After 120 days, these cells die and hemoglobin is metabolized in the spleen and other related tissues. The globin protein is recycled, while the heme portion is excreted. For this to occur, it must be chemically converted to biliverdin, then to bilirubin.
A greenish bile pigment; gall substance.
A greenish pigment in bile formed by the oxidation of bilirubin.
