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)

Hemoglobin
When a hemoglobin molecule is broken apart, the iron pigment is released. This is what is called the -"heme" part of the molecule.
Biliverdin.
its called hemoglobin. it is the pigment which carries oxygen in blood
heomoglobin..... a comlex compound of proteins with iron......
red blood cells is created by a blood protein called Hemoglobin. hope i was helpful
The blood cells are called hemoglobin. The hemoglobin transport oxygen from the lungs to all other parts of the body.
Hemoglobin molecules liberated from red blood cells are broken down into subunits of heme, an iron containing portion, and globin, a protein. The heme further decomposes into iron and a greenish pigment called biliverdin. Biliverdin eventually is converted to an orange pigment called bilirubin.
Hemoglobin is the red pigment, or red color of Blood.
Melanin is a pigment produced by cells called melanocytes. This is the pigment which contributes to skin colour. It also provides some protection from UV light.
Haemoglobin (Hb) is a red coloured protein pigment found within Red Blood CellsIt consists of two basic partsthe iron containing pigment haemthe protein globin
Oxygen is bound to a protein (a respiratory pigment), called hemoglobin.
