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

接着，醛脱氢酶(ALDH) 将有毒的醛转化为无毒的醋酸盐。

The body has an enzyme that breaks down acetaldehyde.

人体有一种分解醛的酶。

I need a flexible bronchoscope and an O.P.A.

给我可曲式气管镜还有氟化醛。

His father died from a chloral hydrate overdose and his mother committed suicide.

他的父亲死于三氯醛水合物过量，母亲死于自杀。

Acetaldehyde generates something called reactive oxygen species.

醛的存在会导致活性氧（ROS）的产生。

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

醛之后再被转换为酸盐并和之前一样，进入线粒体。

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——醛。

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

首先，醇脱氢酶 (ADH) 将酒精转化为有毒的醛。

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

酒醉就是由酒精的代谢产物——醛造成的。

Aldehydes are well known to be toxic.

众所周知，醛有毒。

Ethanol is converted to acetaldehyde and then eventually to acetic acid — the same stuff in vinegar.

醇被转化为醛，然后最终转化为酸——醋中也是如此。

In contrast, frying in butter, olive oil, coconut oil, and lard produced far lower levels of aldehydes.

而用黄油、橄榄油、椰子油或猪油来炸，产生的醛相对要少很多。

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

首先，酶将酒精转化为醛，醛是一种会随着时间的推移损害细胞的物质。

Acetaldehyde is poison. It will kill cells.

醛是毒药。它会杀死细胞。

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（酒精又融水又融油，细胞壁挡不住它）被转化成醛。

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

这些酶分解酒精并将其转化为醛。

So when you heat vegetable oils, free radicals as well as small lipid fragments called aldehydes can form.

所以，当被热时，菜油会产生自由基和一种名叫醛的脂质碎片。

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醛变成酸酯。酸酯的功能和醋很相似，可以轻易地从人体排出。

杯里是水合三氯醛醇和冰茶的混合物。

The most efficient way of making acetaldehyde at the time used a particular catalyst, a thing to kick start the reactions.

当时制造醛最有效的方法使用了一种特殊的催化剂，就是一种动反应的物质。
