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

不饱和脂肪在常温下是液体,通常来源于植物。

双语版 TED-Ed 演讲精选

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

相反,非饱和以双键以双键不规则地连接在一起。

健身知识科普

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

不饱和脂肪被认为是最好的脂肪选择,而反式脂肪则要完全避免。

Worse by far are the trans unsaturated fats.

迄今为止,最糟糕的是反式不饱和脂肪。

Scishow 精选系列

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

所以不饱和脂肪分子没有每个碳原子拥有的氢原子多。

新奇事件簿

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

大豆和发酵大豆制品是超级食品。它们富含蛋白质、纤维和不饱和脂肪。

Scishow 精选系列

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

顺式不饱和脂肪(接下来都称为不饱和脂肪)不易堆积,因此不会形成斑块。

Scishow 精选系列

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

因此,不饱和脂肪往往是液态,也就是油,它们大多取自于植物和鱼类。

Asap SCIENCE 精选

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。我们称这种脂肪为不饱和脂肪。

历年英语六级听力真题(含译文)

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

地中海饮食烹饪中少用饱和脂肪,多用不饱和脂肪,其中橄榄油是用得最多的不饱和脂肪。

Scishow 精选系列

These are almost all manufactured by adding hydrogens or " partially hydrogenating" some unsaturated fat like soybean oil.

这些几乎都是通过增加氢原子或“部分氢化”了一些不饱和脂肪(如大豆油)制造的。

Asap SCIENCE 精选

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。不饱和脂肪的融点比较低,所以它在自然状态下不那么容易凝固,就像植物油一样。

科普小杂文

You can find unsaturated fats in fish, olives, nuts and seeds and still have a place on your plate for so-called good carbs.

你可以从鱼类摄取不饱和脂肪,或是橄欖油、坚果和种子,然后还有空间放俗称的好碳水化合物。

时尚英语张口就来

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

人们应当吃橄榄油等富含不饱和脂肪的食品。

SciShow - Chemistry

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

因此,不饱和脂肪的每个碳原子所含的氢数不多。

化学 Crash Course

So it's an unsaturated fat, but it's really bad for you, that doesn't really jive.

所以它是一种不饱和脂肪,但它对你真的很不好,这并不真正令人兴奋。

化学 Crash Course

Food chemists use hydrogenation to saturate the unsaturated fat, making it spreadable and also stabilizing it.

食品化学家使用氢化作用使不饱和脂肪饱和,使其可涂抹并稳定。

SciShow - Chemistry

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

顺式不饱和脂肪(世界其他地方称之为不饱和脂肪)堆积不好,因此不会形成斑块。

健康小秘密

STEP 3 Eat mostly " good" or unsaturated fats found in nuts and avocados -- or cook with vegetable oils like olive, canola, and corn oil.

使用大部分是“好的”或不饱和脂肪的食物,大部分不饱和脂肪存在于坚果和鳄梨中——或者用蔬菜由烹煮,例如橄榄油,菜籽油和玉米油。

科普小杂文

Not only are unsaturated fats essential for your body, avoiding them in the name of weight loss isn't actually a helpful way to shed unwanted pounds.

不饱和脂肪不仅是你的身体不可或缺的,以减重的名义避开它们其实并不是甩掉赘肉的有效方法。

中文百科

不饱和脂肪

不饱和脂肪是指至少含有一个双键的脂肪或脂肪酸链。如果只有一个双键,则称为单元不饱和脂肪;含有两个双键以上的则称为多元不饱和脂肪。当双键形成时,一对氢原子会被消除,因而与碳原子相结合的氢原子未达到最大值,即“不饱和”。在细胞的新陈代谢中,不饱和脂肪所产生的能量相比饱和脂肪较少。脂肪的不饱和程度越高(双键数量越多),其过氧化的可能性越高,从而越容易对人体健康不利。这时需要抗氧化物来防止这一情况的发生。

英语百科

Unsaturated fat 不饱和脂肪

Amounts of fat types in selected foods
Fig 2. Exemple d'acide gras poly-insaturé : l'acide arachidonique, 20 atomes de carbone et 4 insaturations (4 doubles liaisons)
Fig 4. A. acide trans-9-octadécènoïque B. acide cis-9-octadécènoïque (acide oléique)

An unsaturated fat is a fat or fatty acid in which there is at least one double bond within the fatty acid chain. A fatty acid chain is monounsaturated if it contains one double bond, and polyunsaturated if it contains more than one double bond.

Where double bonds are formed, hydrogen atoms are subtracted from the carbon chain. Thus, a saturated fat has no double bonds, has the maximum number of hydrogens bonded to the carbons, and therefore is "saturated" with hydrogen atoms. In cellular metabolism, unsaturated fat molecules contain somewhat less energy (i.e., fewer calories) than an equivalent amount of saturated fat. The greater the degree of unsaturation in a fatty acid (i.e., the more double bonds in the fatty acid) the more vulnerable it is to lipid peroxidation (rancidity). Antioxidants can protect unsaturated fat from lipid peroxidation.
