Lastly, an iron molecule is added to a protoporphyrin IX via the enzyme ferrochelatase.

最后，铁分子通过亚铁螯合酶添加到IX中。

Therapeutic phlebotomy or bloodletting can be used to manage iron overload, as well as deferoxamine, an iron chelating agent.

治疗性静脉切开术或放血疗法可用于治疗铁超负荷，也可使用铁螯合剂去铁胺。

Yeah, the patient has been administered a chelator called British anti-leukocyte, which will absorb the mercury over the next several days.

是的，患者已经使用了一种螯合剂叫做...英国抗细胞，它将接下来的几天里吸收汞。

To prevent iron overload, iron chelating agents may be given to trap some excess iron and sweep it away through feces or urine.

为了预防铁过载，可使用铁螯合剂清除多余的铁，可通过粪便或尿液排出。

Another cytokine called IL-10 mediates the expression of increased ferritin receptors on the surface of macrophages, which then sequesters even more iron.

另一种叫做介素-10的细胞因子介导巨噬细胞表面的铁蛋的表达增加，如此一来，铁蛋会螯合更多的铁。

Lead poisoning has also been shown to denature enzymes important in heme synthesis, like Delta aminolevulinate dehydratase and ferrochelatase, which are important for heme synthesis.

铅中毒同样也被证明会使血红素合成中重要的酶变性，如Delta-氨基乙酰丙酸脱水酶与亚铁螯合酶这一类对血红素合成至关重要的酶。

That way, any stray atoms of metals from the can will bind to the citric acid, and not to the food inside, a process known as chelation.

这样，罐子里的任何杂散金属子都会与柠檬酸结合，而不是与里面的食物结合，这一过程被称为螯合。

Finally, it needs iron to thrive and replicate, so it produces a siderophore, which is a term used for a group of small, high-affinity, iron chelating compounds that snatch iron from host cells.

最后，它需要人内的铁元素来繁殖，所以它形成一种“铁载”；铁载是指微生物合成并分泌的螯合铁的、用于摄取铁元素的低分子量化合物，他们可以与宿主细胞竞争铁元素。
