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种分子化合物更多，尤其是皮肤上的羧酸。

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化学物质吸引，这种化学物质通常由人类皮肤上的细菌产生。

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。

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

不过它也含有羧酸， 所以让我们继续称之为丁烯酸。

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（这非常理想）。

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，包括羧酸在内的这些化学物质可能是从太空中通过彗星和陨石到达地球的。

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) .

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

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，醋酸是厨房中最常见的羧酸。

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.

羧酸是键合到 OH 基团而不是 R 基团的酮，而醚只是键合到 R 基团而不是氢的醇。
