WebHemoglobin is a conjugated chromo-protein having heme as its prosthetic group. Heme is the prosthetic group, not only of hemoglobin but also of myoglobin, cytochromes etc. Hemoglobin is formed by the combination of heme with globin (protein). Globin is made up of four polypeptide chains (an oligomeric protein). Web26 jan. 2024 · Hemoglobin is broken down into heme, which is converted to biliverdin, and finally into unconjugated bilirubin (which is not water-soluble). In the bloodstream, unconjugated bilirubin binds with serum proteins—most commonly albumin. The unconjugated bilirubin is then taken up by the liver. Figure 1.
