And each of those hemoglobins can bind to four oxygen molecules.

而血红蛋白能4氧分子结合。

Hemoglobin electrophoresis can be done to see which hemoglobin types are present.

血红蛋白电泳可用来鉴别血红蛋白的类型。

The modified cells are then infused back into the body to allow it to start producing functioning hemoglobin.

然后将修改后的细胞注入体内，使其开始产生功能正常的血红蛋白。

When red blood cells do not have enough hemoglobin, oxygen doesn't get to all parts of the body.

当红细胞没有足够的血红蛋白时，氧气就无法到达身体的各部位。

The illnesses are caused by errors in the gene for hemoglobin.

这些疾病是由血红蛋白基因缺陷引起的。

One of the adaptations that the body makes after it's been at high altitude is to make more hemoglobin.

在高海拔地区，身体的其中适应就是制造更多的血红蛋白。

Now your hemoglobin is known as oxyhemoglobin, or HbO2.

现在你的血红蛋白被称为氧合血红蛋白，或 HbO2。

Now, in the blood, each red blood cell has millions of hemoglobin proteins.

在血液中，血红细胞都有数百万的血红蛋白。

So each hemoglobin can carry four oxygen molecules when it's fully saturated.

所以在饱和时，血红蛋白可以携带四氧分子。

These disorders are caused by genetic mutations that prevent the normal production of hemoglobin.

这些疾病是由阻止血红蛋白正常产生的基因突变引起的。

But the fact is, hemoglobin's affinity for oxygen isn't always the same.

但事实是，血红蛋白对氧气的亲和力并不总是样的。

They are made in the bone marrow and contain a special ion-containing protein called hemoglobin.

它们是在骨髓中形成的，含有种叫做血红蛋白的特殊含离子蛋白质。

Normally, hemoglobin is made up of four globin chains, each bound to a heme group.

正常情况下，血红蛋白由4条珠蛋白链组成，条珠蛋白链都血红素基团结合。

Different hemoglobins have different combinations of these chains.

不同的血红蛋白是肽链的不同组合。

They also have a special type of hemoglobin, the molecule in the blood that transports oxygen.

他们同时有着种特殊的血红蛋白，这种分子在血液中负责运输氧气。

Carbon monoxide and oxygen compete to bite hemoglobin in your blood, which stresses the circulatory system.

氧化碳和氧气争先恐后地血液中的血红蛋白结合，这给血液循环系统带来了压力。

These four globin chains combine in different ways to give rise to different kinds of hemoglobin.

这四种珠蛋白链以不同的方式结合，形成不同类型的血红蛋白。

BUT! Partial pressures are only part of what's prodding your hemoglobin to give up the goods.

但是！分压只是促使血红蛋白放弃商品的部分。

If there are three defective alpha genes, there's moderate disease, called hemoglobin H, or HbH, disease.

如果有3α基因异常，则出现中度地中海贫血，即血红蛋白H病（HbH病）。

It says that an increase in carbon dioxide results in hemoglobin proteins releasing oxygen into the tissues.

当血液中的二氧化碳增多时，血红蛋白会把红细胞绑定的氧气释放到人体组织中去。
