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

接着，醛脱氢酶(ALDH) 将有毒醛转化无毒醋酸盐。

The body has an enzyme that breaks down acetaldehyde.

人体有一种醛酶。

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

酒精在体内一种叫做醛物质。

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

给我拿可曲式气管镜还有氟化醛。

Aldehydes are well known to be toxic.

众所周知，醛有毒。

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

首先，醇脱氢酶 (ADH) 将酒精转化有毒醛。

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

他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.

醛存在会导致活性（ROS）生。

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

醛之后再被转换酸盐并和之前一样，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致癌物——醛。

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

酒醉就是由酒精代谢物——醛造成。

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

所以，当被加热时，菜油会生自由基和一种名叫醛脂质碎片。

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

首先，酶将酒精转化醛，醛是一种会随着时间推移损害细胞物质。

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。

Acetaldehyde is poison. It will kill cells.

醛是毒药。它会杀死细胞。

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

这些酶酒精并将其转化醛。

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，生醛相对要少很多。

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。酸酯功能和醋很相似，可以轻易地从人体排出。

In those glasses is a combination of chloral hydrate, ethanol, and iced tea.

杯里是水合三氯醛醇和冰茶混合物。

This is what causes someone to become red when they drink, and it causes hang overs.
