Bilirubin vs. Hematoidin

Bilirubinnoun

(biochemistry) A bile pigment that is a product of the breakdown of the heme portion of hemoglobin (which occurs within macrophages as they digest red blood cells), and which is responsible for the yellowish color seen in bruises. Extremely high levels of bilirubin may cause jaundice.

Bilirubinnoun

A reddish yellow pigment present in human bile, and in that from carnivorous and herbivorous animals; the normal biliary pigment.

Bilirubinnoun

an orange-yellow pigment in the bile that forms as a product of hemoglobin; excess amounts in the blood produce the yellow appearance observed in jaundice

Bilirubinnoun

an orange-yellow pigment formed in the liver by the breakdown of haemoglobin and excreted in bile.

Bilirubin

Bilirubin (BR) is a yellow compound that occurs in the normal catabolic pathway that breaks down heme in vertebrates. This catabolism is a necessary process in the body's clearance of waste products that arise from the destruction of aged or abnormal red blood cells.

Hematoidinnoun

(obsolete) bilirubin

Hematoidinnoun

A crystalline or amorphous pigment, free from iron, formed from hematin in old blood stains, and in old hemorrhages in the body. It resembles bilirubin. When present in the corpora lutea it is called hæmolutein.

Hematoidinnoun

an orange-yellow pigment in the bile that forms as a product of hemoglobin; excess amounts in the blood produce the yellow appearance observed in jaundice
