<prompt> All the statement about lactoferrin are true, EXCEPT:It has great affinity for ironIt transpos iron for erythropoiesisIt is present in exocrine secretions of bodyIt is present in secondary granules of neutrophils  <response>: Transpo of iron for erythropoesis is done by transferin and not by Lactoferin. Lactoferrin is closely related in structure to plasma iron transpo protein transferrin, and binds to excess iron. It prevents the growth of bacterial and viral microorganism and tumors which require iron for its growth. Lactoferrin a bioactive glycoprotein, is one of the bodys most powerful immunodefensives. It is found in breast milk, body fluids such as saliva, tears, nasal secretions, intestinal fluids such as bile and secondary granules of neutrophils.
