动物体内“贮存铁”虽几乎存在于所有的细胞内,但主要还是存在于网状内皮细胞和肝细胞内,它以铁蛋白及合铁血黄素两种形式出现,占体内总铁量的27％。 铁蛋白铁是可溶性的,它沉积于脱铁铁蛋白外壳内,形成一个结晶核心。含铁血黄素则是铁蛋白的降解产物,即铁蛋白丧失部分蛋白外壳后的聚集体。共所含的铁晶核不再与完整 Although the “storage iron” in animal body exists in almost all cells, it mainly exists in reticuloendothelial cells and hepatocytes. It appears in two forms of ferritin and hemosiderin, accounting for 27% %. Ferritin is soluble in iron and is deposited within the apoferritin shell to form a crystalline core. Hemoside is a degradation product of ferritin, an aggregate of ferritin that has lost part of its protein shell. The total contained iron nuclei are no longer complete
