Carboxylic acids are in the mix, too, adding notes of cheese.

羧酸也混在其中增加了芝士的味道。

Now the study found that 50 molecular compounds were higher in mosquito magnets especially carboxylic acid on the skin.

现研究发现，招蚊子喜爱的人群中有50种分子物更多，尤其是皮肤上的羧酸。

It's also got the carboxylic acid though, so let's go ahead and call it butenoic acid.

过它也含有羧酸， 所以让我们继续称之为丁烯酸。

Also, mosquitoes are most attracted to a kind of chemical called carboxylic acid, which is usually produced by bacteria on human skin.

此外，蚊子最容易被一种名为羧酸的学物质吸引，种学物质通由人类皮肤上的细菌产生。

Numbering the other way, 1-2-3-4, the carboxylic acid is on carbon 1 (that's pretty ideal).

以另一种方式编号， 1-2-3-4， 羧酸在碳 1 上（理想）。

Things like long chain amines have a fishy or rotten smell, and some people say that long chain carboxylic acids smell like goats.

长链胺之类的东西有腥味或腐臭味，有人说长链羧酸闻起来像山羊。

Carboxylic Acids are the acid part of amino acids, which make up proteins, which make up, you, so they're pretty important.

羧酸是氨基酸的酸性部分， 它构成蛋白质，构成你，所以它们重要。

Some have suggested that these chemicals, including carboxylic acids, may have arrived on Earth from space, traveling via comets and meteorites to the forming planet.

一些人认为，包括羧酸在内的些学物质可能是从太空中通过彗星和陨石到达地球的。

Acetone has a ketone group and it's called 'acetone' because it was derived from acetic acid, which is vinegar, the most common carboxylic acid in your kitchen.

丙酮有一个酮基，之所以称为“丙酮”，是因为它是从醋酸中提取的，醋酸是厨房中最见的羧酸。

Carboxylic acids are a type of organic compound characterized by a carbon (C) atom doubly bonded to an oxygen (O) atom and singly bonded to a hydroxyl group (-OH) .

羧酸是一种有机物，其特征是一个碳（C）原子与一个氧（O）原子双键结，并与一个羟基（-OH）单键结。

While carboxylic acids are ketones bonded to an OH group instead of an R group, and ethers are just alcohols bonded to an R-group instead of a hydrogen.

羧酸是键到 OH 基团而是 R 基团的酮，而醚只是键到 R 基团而是氢的醇。

The most weighted of all is the carboxylic acid functional group, so no matter what else is on a six carbon chain, if there's a carboxylic acid, then it's a hexanoic acid.

最重要的是羧酸官能团，所以无论六碳链上还有什么， 如果有羧酸， 那么它就是己酸。

After that happens, the liver turns the fatty acids into ketone bodies, like acetoacetic acid and beta hydroxybutyric acid; acetoacetic acid is a ketoacid because it has a ketone group and a carboxylic acid group.

此后，肝把脂肪酸转成酮体，比如乙酰乙酸、β-羟基丁酸；乙酰乙酸是一种酮酸，因为它有酮基团和羧酸基团。

If it's a six carbon chain with a carboxylic acid on it and an alcohol on one of the other carbons, our name has to do two things: identify that the hydroxyl group is there and identify where it is.

如果它是一个六碳链， 上面有一个羧酸， 另一个碳上有一个醇，我们的名字必须做两件事：确定羟基的存在并确定它的位置。
