<prompt> Transpo form of iron is-TransferrinFerritinApoferritinLactoferrin  <response>: Ref: Satyanarayana, Ed. 1st, Pg-189,459 Transferrin Siderophilin is a glycoprotein which transpos iron in the circulation. Each transferrin molecule can bind with two atoms of ferric ion Fe3. As free iron is toxic to the body, binding of iron to transferrin reduces toxicity apa from transpoing iron from gut to target tissues. Plasma transferrin can bind with 400u g of irondl plasma. This is known as Total Iron Binding Capacity TIBC of plasma. Ferritin is the storage form of iron in mucosal cells temporarily, liver, spleen and bone marrow.
