A for acetyl, and spir for meadowsweet, whose botanical name is Spiraea ulmaria.

A 代表乙酰基，spir 代表绣线菊，名称是 Spiraea ulmaria。

Under normal conditions, cholinergic neurons in the brain, synthesize acetylcholine from acetyl coenzyme A (acetyl CoA) and choline, in a reaction catalyzed by an enzyme choline acetyltransferase (CAT).

正常情况下，大脑中胆碱能神经元从乙酰辅酶A（乙酰辅酶A）和胆碱，由胆碱酶催化反应乙酰转移酶（CAT）。

Epigenetics—currently one of molecular biology's hottest topics —is a process by which genes are activated or deactivated by the presence or absence of chemical structures called methyl and acetyl groups.

表现遗传——目前分子生最热话题之一——是这样一个过程，基因激活或是失效取决于被称为甲基和乙酰基化结构存在或是消失。

If you stopped consuming food, within 6 hours your body will be breaking down glycogen into glucose and fat into acetyl CoA to keep your bioloical processes at work.

如果停止进食， 体将在 6 小时内将糖原分解为葡萄糖，并将脂肪分解为乙酰辅酶 A， 以保持生过程正常运转。

We convert glucose to pyruvate through the process of glycolysis, and then we convert pyruvate to acetyl-CoA, which then gets burned, gets oxidized for energy, to produce energy through the krebs cycle.

通过糖酵解过程将葡萄糖转化为内酮酸盐，人体接着将丙酮酸盐转换成乙酷辅酶 A，后者紧接着被氧化，最后再通过克氏循环转换成能量。

It replaced one of salicylic acid's hydroxyl group — that's an oxygen and hydrogen bonded to a carbon — with an acetyl group, which is two carbons, one double-bonded to an oxygen and the other bonded to three hydrogens.

它用乙酰基取代了水杨酸一个羟基——氧和氢与碳结合——乙酰基是两个碳，一个与氧双键结合，另一个与三个氢结合。
