铁的转运铁在体内的运输过程与铁的吸收、利用、贮存、排泄关系密切。在各铁池间的交换中起媒介和载体作用。一、细胞外转运铁在其结束吸收过程,离开肠粘膜细胞,进入血浆后,以Fe~(+++)形式与运铁蛋白(Tf)结合,运铁至全身各需铁组织。Tf是β_1球蛋 Iron transport iron in the body of the transport process and iron absorption, utilization, storage, excretion close. In the iron pool between the exchange of media and carrier role. First, the extracellular transport of iron at the end of its absorption process, leaving the intestinal mucosal cells, into the plasma, with Fe ~ (+++) form and transferrin (Tf) binding, transport iron to the body all need iron tissue. Tf is a beta 1 egg
