Six hours later the animal was sacrificed and the isotope concentration in the haemin and the globin analysed. WebProtoporphyrin synthesis begins and ends in the mitochondria of the RBC. A few steps in the middle of protoporphyrin synthesis takes place outside of the mitochondria. Iron is supplied to RBCs from plasma by the iron transfer protein transferrin. 2/3 of total body iron goes to hemoglobin synthesis.
