This is because sebum is composed of both saturated and unsaturated fatty acids.

因为皮是由肪酸非肪酸共同组成的。

Worse by far are the trans unsaturated fats.

迄今为止，最糟糕的是反式不肪。

Unsaturated fat is usually liquid at room temperature and generally comes from vegetable sources.

不肪在常温下是液体，通常来源于植物。

Unsaturated bonds are more reactive, and it is here that ozonolysis does its work.

不键反应性更强，这就是臭氧分解的作用。

But they only consume the saturated fats, leaving the unsaturated ones behind.

但他们只以肪酸为，剩下了非肪酸。

So unsaturated fats don't have as many hydrogens as they could have per carbon atom.

所以不肪分子没有每个碳原子拥有的氢原子多。

Soybeans and fermented soybean products are superfoods. They are rich in protein, fibre and unsaturated fats.

大豆发酵大豆制品是超级品。它们富质、纤维不肪。

Unsaturated fats, on the other hand, contain double bonds that create an irregular kink in their structure.

相反，非以双键以双键不规则地连接在一起。

Unsaturated fats are regarded as the best fat option, whereas trans fat is to be avoided completely.

不肪被认为是最好的肪选择，而反式肪则要完全避免。

When darkened and unsaturated for a low-key look, they feel calm, fresh and comfortable to the modern taste.

当颜色亮度度变低，就会让人感到平静、清新适应现代品味。

So unsaturated fats tend to be liquid, making them oils, and come mostly from plants and fish.

因此，不肪往往是液态，也就是油，它们大多取自于植物鱼类。

The carbons double bond with each other so that fewer hydrogen can fit and we call this unsaturated fat.

每个碳原子之间都有双键连接，这样氢很难嵌入碳原子之间。我们称这种肪为不肪。

It can be divided into two main groups - saturated and unsaturated.

它可以分为两大类——的不的。

Cis unsaturated fats (which the rest of the world just calls unsaturated fats) don't stack well and so don't form plaques.

顺式不肪（接下来都称为不肪）不易堆积，因此不会形成斑块。

Mediterranean cooking uses smaller amounts of saturated fat and higher amounts of unsaturated fat, mostly in the form of olive oil.

地中海饮烹饪中少用肪，多用不肪，其中橄榄油是用得最多的不肪。

Swapping out saturated fats for unsaturated ones, like those found in nuts, is usually beneficial.

用不肪替换肪，就像坚果中的那种，对身体有益。

People should eat foods rich unsaturated fats such as olive oil.

人们应当吃橄榄油等富不肪的品。

Like, I'm not getting into the medical details of the difference between saturated and unsaturated.

就像，我不会深入了解肪不肪之间的区别的医学细节。

So unsaturated fats don’t have as many hydrogens as they could have per carbon atom.

因此，不肪的每个碳原子所的氢数不多。

Not so fast, unsaturated fat has a lower melting point and so its natural state is less solid, like vegetable oil.

别这么快下定论。不肪的融点比较低，所以它在自然状态下不那么容易凝固，就像植物油一样。
