Myoglobin measurement with enzyme

Fig. 44.6. Iron metabolism. Iron is absorbed from the diet, transported in the blood in transferrin, stored in ferritin, and used for the synthesis of cytochromes, iron-containing enzymes, hemoglobin, and myoglobin. It is lost from the body with bleeding and sloughed-off cells, sweat, urine, and feces. Hemosiderin is the protein in which excess iron is stored. Small amounts of ferritin enter the blood and can be used to measure the adequacy of iron stores. RE = reticuloendothelial.
