How is hemoglobin synthesized
WebHaemoglobin is a protein consisting of 4 polypeptide chains. Each polypeptide chain is encoded by 438 bases. How many amino acids are there in the Haemoglobin protein? a) 195 b) 584 c) 1,752 d) 3,504. What is the difference between fetal hemoglobin and adult hemoglobin, and what purpose does this difference serve? Web4 nov. 2024 · In the bloodstream, unconjugated bilirubin binds to albumin to facilitate its transport to the liver. Once in the liver, glucuronic acid is added to unconjugated bilirubin by the enzyme glucuronyl transferase. This forms conjugated bilirubin, which is soluble. This allows conjugated bilirubin to be excreted into the duodenum in bile.
