First, an enzyme called ADH turns alcohol into acetaldehyde, which is toxic.

首先，醇脱氢酶 (ADH) 将酒转化为有毒的。

Also, oral bacteria convert ethanol to acetaldehyde which is a carcinogen.

此外，口腔微生物群可将醇转化为致癌物——。

Alcohol breaks down in the body into a substance called acetaldehyde.

酒在体内分解为一种叫做的物质。

The acetaldehyde then gets converted to acetate and goes into the mitochondria like last time.

后再被转换为酸盐并一样，进入线粒体。

A hangover is suspected to be the result of alcohol being metabolized into acetaldehyde.

酒醉就是由酒的代谢产物——造成的。

Then, an enzyme called ALDH converts the toxic acetaldehyde to non-toxic acetate.

接，脱氢酶(ALDH) 将有毒的转化为无毒的醋酸盐。

The body has an enzyme that breaks down acetaldehyde.

人体有一种分解的酶。

Ethanol doesn't need insulin to get into the cell, it just diffuses in there and is converted to acetaldehyde.

醇不需要胰岛素进入细胞，它直接融进去肝细胞里面（酒又融水又融油，细胞壁挡不住它）被转化成。

If acetaldehyde sounds familiar that maybe because it's similar to formaldehyde. It's toxic. That's why it triggers the immune responds.

你可能觉得醇似曾相识，那是因为他甲一样，有毒。这就是为什么我们的免疫系统会产生反应。

And the second quickly turns acetaldehyde into acetate, which is similar to vinegar and easy for the body to eliminate.

而第二种酶此时会快速地将变成酸酯。酸酯的功能醋很相似，可以轻易地从人体排出。

First, enzymes convert the alcohol to acetaldehyde, a substance that can damage cells over time.

首先，酶将酒转化为，这种物质会随时间损害细胞。

These enzymes break down alcohol and convert it into something called acetaldehyde.

这些酶分解酒并将其转化为。

Acetaldehyde is the same chemical byproduct that we make that's very toxic.

是我们体内产生的一种同样非常有毒的化学副产品。

So what happens is it's a variation enzyme that causes a buildup of acetaldehyde.

其结果是，这是一种变异的酶，会导致在体内积聚。

It builds up quickly and acetaldehyde is toxic.

它会迅速积累，而是有毒的。

See if you have an issue with dopamine and motivation because candida produces something called acetaldehyde.

检查你是否存在多巴胺动机问题，因为念珠菌会产生一种叫做的物质。

But I found this fascinating because as I was researching acetaldehyde, it's like 35% to 45%.

但我发现这很有趣，因为在我研究时，发现其含量大约在35%到45%间。

So when you drink alcohol, some of the alcohol turns into acetaldehyde in the gut.

所以当你饮酒时，部分酒会在肠道内转化为。

And what they did is they went in, modified bacteria to break down acetaldehyde in the gut.

他们所做的是，改造了细菌，使其能够在肠道中分解。

If you've got the flushing reaction, which means you can't metabolize or break down the main metabolites of alcohol, acetaldehyde.

如果你出现脸部潮红反应，说明你无法代谢或分解酒的主要代谢物。
