However, this condition can almost always be prevented. stream We don't support your browser. The excess turnover of red blood cells results in increased heme metabolism, producing large amounts of bilirubin that overwhelm the conjugating machinery, leading to decreased excretion and clinical jaundice.

It is first converted to biliverdin and then to unconjugated bilirubin within macrophages in the reticular endothelial system.5 Unconjugated bilirubin is lipid soluble and passes easily through cell membranes to bind to albumin in serum, whereas free (unbound) bilirubin is taken up by liver hepatocytes and converted to conjugated bilirubin.4,6 Conjugated bilirubin is water soluble and is transported from liver hepatocytes into the biliary tract system where it passes to the intestines and is excreted into the stool.
