Study Notes
Iron Transport and Absorption
- Transferrin is the protein responsible for transporting iron in the blood.
- The small loss of iron each day comes from normal bodily functions such as shedding of skin and mucosal cells, and loss of iron-containing molecules in sweat and urine.
- Ceruloplasmin is the protein responsible for oxidizing iron in the intestine to a form that can be absorbed by the body.
