But at the time no one knew why amyl nitrite worked only that it did.

但当时没有人知道为什么亚硝酸戊酯会起作用。

The main suspect bad compounds put specifically in processed meat are nitrates and nitrites.

加工过的肉类中，主要被怀疑有害的化物是硝酸盐和亚硝酸盐。

On the other hand, nitrites help to prevent bacterial growth that can cause botulism.

另一方面，亚硝酸盐有助于防止细菌生长的特性可导致肉毒中毒。

Well, Nitrosamines are the cancerous compounds suspected to form from the nitrate and nitrites found in processed meat.

人们怀疑亚硝胺是由加工肉类中的硝酸盐和亚硝酸盐形成的癌症化物。

These nitrites react with amino acids during cooking, forming nitrosamines, which are known carcinogens, increasing your risk of developing cancer.

这些亚硝酸盐在烹饪过程中与氨基酸发生反应，形成亚硝胺，亚硝胺是已知的致癌物质，会增加患癌症的风险。

Now, there are some major issues with the nitrate nitrite idea.

现在，硝酸盐亚硝酸盐的观点有一些主要的问题。

They didn't contain any nitrate, no nitrite.

它们不含任何硝酸盐，也没有亚硝酸盐。

Direct nitrite donors, in my opinion, work better, but they are harder to time.

在，直接的亚硝酸盐供体效果更好，但它们更难掌握使用时机。

That's not- It's not like, for example, if I take L-citrulline or nitrite.

那不是——比如说，如果服用L-瓜氨酸或硝酸盐。

(video) Normally, your urine doesn’t have any nitrite in it, although it’s chock full of nitrate.

（视频）通常，你的尿液中不含亚硝酸盐，尽管它含有大量的硝酸盐。

When your body metabolizes this stuff, NDMA breaks down into nitrite (NO2-) and methyl radicals (CH3).

当你的身体代谢这些东西时，N-二甲基亚硝胺会分解成亚硝酸根(NO2-)和甲基自由基(CH3)。

And the bacteria perform this metabolism of nitrate into nitrite and nitric oxide.

细菌将硝酸盐代谢成亚硝酸盐和氮氧化物。

I mean, they don't have the same nitrite content as arugula, so it was not a surprise.

意思是，它们的硝酸盐含量不像芝麻菜那么高，所以这并不令人意外。

Part of this cycle takes place in the mouth, so there is naturally plenty of nitrite in our saliva.

这个循环的一部分发生在口腔中，所以们的唾液中自然有大量的亚硝酸盐。

This paper refers to both nitrate and nitrite as nitric oxide therapeutics.

这篇论文将硝酸盐和亚硝酸盐作为一氧化氮的治疗方法。

But by around 1880, doctors began to realize that nitroglycerine was even more effective and faster acting for heart problems than amyl nitrite.

但是到了 1880 年左右，医生们开始意识到，硝酸甘油比亚硝酸戊酯对心脏病的疗效更有效、作用更快。

But, the acidic nature of our stomach is suspected to allow nitrates and nitrites to turn into nitrosamines in the body during digestion.

但是，人们怀疑们的胃的酸性是让硝酸盐和亚硝酸盐在消化过程中在体内转化为亚硝胺的原因。

Like the pH of your pee, the concentration of various compounds, and its levels of certain cells or molecules, such as nitrite.

就像尿液的pH值， 各种化物的浓度，以及亚硝酸盐等特定细胞或分子的水平。

The ammonia-laden water is therefore pumped through colonies of bacteria which, given enough oxygen, will convert the ammonia into nitrite and nitrate.

因此，富含氨的水被泵入细菌菌落，如果有足够的氧气， 细菌菌落会将氨转化为亚硝酸盐和硝酸盐。

A diet high in sodium nitrites may also lead to a decrease in your body's ability to transport oxygen properly in your red blood cells.

高亚硝酸钠的饮食也可能会降低你身体在红细胞中输送氧气的能力。
