Enzymatic Actions in the SI ,[object Object],[object Object],[object Object],[object Object],*Bilirubin is the main bile pigment that is formed from the breakdown of heme in red blood cells. The broken down heme travels to the liver, where it is secreted into the bile by the liver. Bilirubin is passed in the feces and gives it the yellow-brown color. Excess bilirubin causes jaundice and stains skin, eyes and nails yellow.
