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

在血液中，每个血红细胞都有数百万血红白。

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

但导致血红白水平低或贫血最常见原因是缺铁。

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

一氧化碳会永久地你血液中血红白结合，阻止氧气结合。

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，含有一种叫做血红白特殊含离子白质。

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

这些疾病是由阻止血红白正常产基因突变引。

Now hemoglobin is made up of hemes and globins.

血红白由血红素珠白构成。

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

所以在饱和时，每一个血红白可以携带四个氧分子。

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

这些疾病是由血红白基因缺陷引。

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

但事实是，血红白对氧气亲和力并不总是一样。

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

血红白电泳可用来鉴别血红白类型。

Finally, the diagnosis is confirmed by genetic testing to look for hemoglobin gene mutations.

最后，可以通过基因检测寻找异常血红白基因进行确诊。

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

而一个血红白能4个氧分子结合。

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

镰状细胞性贫血影响红细胞中一种白质。这种白质被称为血红白。

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

一氧化碳和氧气争先恐后地血液中血红白结合，这给血液循环系统带来了压力。

Hemoglobin is the carrier molecule which carries the oxygen obtained during the process of respiration.

血红白是携带呼吸过程中获得氧气载体分子。

Hemoglobin is actually made up of four peptide chains, each bound to a heme group.

血红白实际上是由四条肽链构成，其中每条肽链均亚铁血红素结合。

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

如果有3个α基因异常，则出现中度地中海贫血，即血红白H病（HbH病）。

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

当血液中二氧化碳增多时，血红白会把红细胞绑定氧气释放到人体组织中去。

Most important among these are oxygen molecules, which bind to the hemoglobin in your red blood cells.

其中最重要就是氧分子，氧分子红细胞中血红白结合。

Another adds an iron-containing molecule called heme, which their team says is key to its meaty flavor.

还有公司添加了含铁血红白分子，并称这是“肉味”关键。
