So, they cannot make enough haemoglobin.

因此，们不能制造足够蛋白。

Never mind, said he, chuckling to himself. The question now is about haemoglobin.

这没有什么，地笑了笑，现在要谈是色蛋白质问题。

The carbon monoxide permanently binds to haemoglobin in your blood, blocking oxygen from binding.

一氧化碳会永久地与你液中蛋白结合，阻止氧气结合。

But the most common cause of low haemoglobin levels, or anaemia, is lack of iron.

但导致蛋白平低或贫最常见原因是缺铁。

Sickle Cell Anemia affects a protein in the red blood cells. This protein is called haemoglobin.

镰状细胞性贫影响细胞中一种蛋白质。这种蛋白质被称为蛋白。

The body needs a particular amount of haemoglobin to work correctly.

人体需要一定数量蛋白才能正常工作。

This means they have fewer haemoglobin molecules to help move and hold oxygen.

这意味着它们有较少蛋白分子来帮助运输和保存氧气。

There are many reasons why haemoglobin levels may drop.

导致蛋白平下降原因有很多。

And they become sticky. Bad haemoglobin also causes red blood cells to die more quickly than healthy red blood cells.

并且液会变得粘稠。不良蛋白还会导致细胞比健康细胞更快死亡。

It's plant-based haemoglobin so it's that kind of irony taste, you know, that you have with meat.

它是基于植物蛋白， 所以它有一种讽刺味道， 你知道，你有肉。

They can do this because inside the red blood cells, there is a very important molecule called haemoglobin.

它们之所以能做到这一点，是因为在球内部，有一种非常重要分子，叫做蛋白。

The reason is that, besides its well-known role in haemoglobin, the oxygen-transporting molecule in the blood, iron is also involved in many aspects of brain development.

因为除了在液中氧气运输分子——蛋白中发挥着众所周知作用外，铁元素还在许多方面参与了大脑发育。

If we had an approach that could go beyond cutting and essentially find and replace, correct that defect and restore the normal haemoglobin protein, that should be a definitive cure.

如果我们有一种方法可以超越切割并从根本上找到和替换，纠正该缺陷并恢复正常蛋白，那应该是一种彻底治愈方法。
