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

A 代乙酰基，spir 代绣线菊，其植名称是 Spiraea ulmaria。机翻

2.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，大脑中的胆碱能神经元从乙酰辅酶A（乙酰辅酶A）和胆碱，由胆碱酶催化的反应乙酰转移酶（CAT）。

3.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.

现遗传——目前分最热的话题之一——是这样一个过程，基因的激活或是失效取决于被称为甲基和乙酰基的化结构的存在或是消失。

4.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.

如果您停止进食， 您的身体将在 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， 以保持您的过程正常运转。机翻

5.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。

6.Cellular respiration occurs in three simultaneous phases, where glucose is broken down by glycolysis and other catabolic reactions; and then turned into pyruvic acid and acetyl CoA; and finally ushered into the Kreb's cycle.

细胞呼吸发在三个同时的阶段，其中葡萄糖被糖酵解和其他分解代谢反应分解；然后转化为丙酮酸和乙酰辅酶 A；最后进入克雷布循环。
