    The hemoglobin in red blood cells contains what’s called a porphyrin ring. The center of which holds iron which can bind oxygen. When the red blood cells are destroyed, the porphyrin is degraded. The complete depredation of the porphyrin goes through many stages. One stage is bilirubin which is the a major constituent of bile.
