铁蛋白(ferritin)为机体内一种贮存铁的蛋白质,在人体铁的贮存和转化中起着十分重要的作用。正常情况下,人体铁的吸收及排泄主要通过控制铁的吸收量进行调节,贮存铁与血清铁之间保持着动态平衡。当机体需铁量增加或排泄量过多时,除由贮存铁补充外,由于小肠粘膜含铁量减少,可促进肠粘膜对铁的吸收。 Ferritin, an iron-storing protein in the body, plays an important role in the storage and transformation of human iron. Under normal circumstances, the absorption and excretion of human iron is mainly controlled by the absorption of iron to adjust the storage of iron and serum iron to maintain a dynamic balance between. When the body needs to increase the amount of iron or excessive excretion, in addition to the storage of iron supplements, due to reduced iron content in the small intestine mucosa, intestinal absorption of iron can promote intestinal mucosa.
