世界卫生组织的国际癌症研究机构的报告确认红素铁中可疑的化合物之一。

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

正常情况下，红白由4条珠白链组成，每条珠白链都与一红素基团结合。

Without this enzyme, porphobilinogen cannot be converted to hydroxymethylbilane and the heme synthesis pathway can't continue.

没有了这酶，卟胆原不能够转化为羟甲基胆素，红素合成途径中断。

The main methods of treatment are glucose and heme.

主要的治疗措施为使用葡萄糖和红素。

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的红白分子，并称这“味”的关键。

There are four globin subunits, typically two alpha and two beta, and each one has its own heme group.

它含有四白亚基，通常2α亚基和2β亚基，每亚基都含有红素分子。

Heme iron is said to increase your risk for heart disease, and even cancer, particularly colon cancer.

据说红素铁会增加患心脏病甚至癌症的风险，尤其结肠癌。

Depending on the person and their lifestyle, iron stores can deplete rapidly when you stop ingesting heme iron.

根据人及其的生活方式，当你停止摄入红素铁元素时，体内的铁元素会迅速耗尽。

And ten tongue twisters later, we've got a completed heme.

在这十绕口令之后，我们就得到了完整的红素。

Scientists found that its belly contained iron, bound up in a molecule called heme—the compound in blood that carries oxygen.

科学家在其腹部发现含有铁, 组成了一种被称为亚铁红素的分子，这一种在液中携带氧气的化合物。

Without Delta-ALA synthase, there's a build up of iron and not enough normal heme production.

若缺乏Delta-ALA合酶，就会导致铁的堆积及正常红素合成的减少。

Now with sideroblastic anemia, there's defective protoporphyrin synthesis, which results in impaired incorporation of iron to form heme.

在铁粒幼细胞性贫中，原卟啉合成存在缺陷，导致铁结合形成红素的能力受损。

Each hemoglobin molecule contains four heme groups with iron cores to which oxygen binds.

每红白分子包含四红素基，铁核与氧结合。

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

It's called 'heme' and it's a key ingredient in their wheat, coconut and potato-based meat duplicate.

它被称为“ 红素” ， 他们的小麦、椰子和马铃薯制品的关键成分。

Now hemoglobin is made up of hemes and globins.

红白由红素与珠白构成。

Heme, of course, is the reason your blood can carry oxygen.

当然，红素液能够携带氧气的原因。

Zooming in even closer, each hemoglobin molecule is made up of four smaller heme molecules, which have iron right in the middle.

再放大看，每红白分子由四更小的红素分子组成，它们中间有铁。

This oxygen is bound to hemoglobin, which consists of an iron-containing pigment called heme and a protein part called globin.

这些氧气与红白结合，红白由叫做红素的含铁的色素和叫做珠白的白质部分组成。
