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原卟啉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疗法用于治疗铁超负荷，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，患者已经用了一种螯合剂叫做...英国抗白细胞，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，用铁螯合剂清除多余的铁，通过粪便或尿液。

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

另一种叫做白介素-10的细胞因子介导巨噬细胞表面的铁蛋白受体的表达增加，如此一来，铁蛋白受体会螯合更多的铁。

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.

铅中毒同样被证明会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原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，它需要人体内的铁元素来繁殖，所以它形成一种“铁载体”；铁载体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，他们以与宿主细胞竞争铁元素。
