What is Transferrin in the blood is saturated with iron normally by: and explain in detail?
Transpo of Fe2+ into the enterocytes occurs divalent metal transpoer 1 (DMT1). Some is stored in ferritin. A protein called hephaestin (Hp) is associated with ferropoin 1. It is not a transpoer itself, but it facilitates basolateral transpo. In the plasma, Fe2+ is conveed to Fe3+ and bound to the iron transpo protein transferrin. This protein has two iron-binding sites. Normally, transferrin is about 35% saturated with iron, and the normal plasma iron level is about 130 microg/dL (23 mumol/L) in men and 110 micro g/dL (19 mumol/L) in women.
