The red pulp of the spleen is where old and defective blood cells are destroyed and their parts - the hemoglobin, the heme chain, and the iron - are either broken down or recycled.

红髓是衰老和缺陷的血细胞被破坏的场所，它们的碎片：血红蛋白、血红素链和铁要么被分解，要么被循环利。

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，每条珠蛋白链都与一个血红素基团结合。

Kresser mentions that the proposed mechanisms thought to be behind processed meat causing cancer are N-nitroso compounds, heme iron, TMAO, Neu5GC, and heterocyclic amines formed from cooking.

Kresser 提到，加工过的肉类食品包含了这些致癌因素，亚硝基化合物、血红素铁、氧化三甲胺、羟乙酰神经氨酸以及在烹调过程中产生的杂环胺。

The Impossible Whopper imitates the taste of meat by using heme, an iron-rich protein, extracted from soyabean roots and mixed with other vegetable ingredients.

That iron-containing myoglobin starts out red, but as it heats up the iron in its heme group oxidizes and it turns this brown color.

A, speaking of hemisphere, heme is one of those weird words, but it means half basically, and the world is divided into different hemispheres.

说到半球， heme 这个词有点怪，但它基本上就是指一半， 世界被划分为不同的半球。

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

放大看，每个血红蛋白分子由四个更小的血红素分子组成，它们中间有铁。

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血红素的分子，这是一种在血液中携带氧气的化合物。

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血红蛋白分子，并称这是“肉味”的关键。

An artist created this little heme guy for me, but thanks to the course on Skillshare by Jake Bartlett, I was able to make this simple animation which hopefully will be the start of making higher quality video for real.

一位艺术家为我创造了这个小血红素家伙，但感谢杰克·巴特利特在 Skillshare 上的课程，我能够做这个简单的动画，希望这将是制作高质量视频的开始。

The main methods of treatment are glucose and heme.

主要的治疗措施为使葡萄糖和血红素。

Though process to create heme requires 8 enzymes and uses up the main protein for collagen, glycine, as well as vitamin B6, zinc and of course, iron.

然而，制造血红素的过程需要8种酶，并消耗胶原蛋白、甘氨酸、维生素B6、锌，当然还有铁的主要蛋白质。

Now, heme synthesis is also called porphyrin synthesis and when halted, it result in the buildup of one of its precursors molecules.

血红素合成也被称为卟啉合成，如果停止，这会导致它的一个前体分子的积累。

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

当然，血红素是血液能够携带氧气的原因。

These disorders all affect the production of heme which is a major component of red blood cells.

Well, one of the initial studies looking at that idea that heme iron causes cancer, fed calcium deficient rats a heme iron rich diet and found that indeed, these rats developed precancerous lesions in their colon.

在一项关于血红素铁能致癌的初步研究中，钙缺乏的老鼠被喂食富含血红素铁的食物，该研究发现，这些老鼠的结肠发生了癌前病变。

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

没有了这个酶，卟胆原不能够转化为羟甲基胆素，血红素合成途径中断。

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

Growing people and people who are growing people, surely need more easily absorbed iron, but older people might be tempted to avoid good sources of heme iron for some of the reasons I just talked about.

正在长身体的人（孩子）和需要养孩子的人（家长/孕妇），当然需要更容易吸收的铁，但老年人可能会避免良好的血红素铁来源，这是我刚才提到的一些原因。
