原声例句
WIL生活启示录 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。 WIL生活启示录 Pyruvate enters the mitochondria, Mitochondria is like the coal furnace of your cell because it converts the Pyruvate to Acetyl-CoA, then burns that in the TCA cycle to produce a bunch of energy in the form of ATP. 丙酮酸进入线粒体，线粒体就像是你的细胞的锅炉，它把丙酮酸转换成乙酰辅酶 A，然后在三梭循环中把它烧掉，以 ATP 的形式来产生一些能量。 医学英语视频 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）。 AsapSCIENCE - Food 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， 以保持您的生物过程正常运转。

乙酰辅酶A Acetyl-CoA（重定向自Acetyl CoA）
    乙酰辅酶A（英语：acetyl-CoA）是活化了的乙酸，由乙酰基（CH3CO-）与辅酶A的巯基以高能的硫酯键相连。乙酰辅酶A是脂肪酸的β-氧化及糖酵解后产生的丙酮酸脱羧后的产物。 在三羧酸循环的第一步，乙酰基转移到草酰乙酸中，生成柠檬酸，因此这个循环也称作「柠檬酸循环」。

Acetyl-CoA 乙酰辅酶A（重定向自Acetyl CoA）
 Acetyl coenzyme A or acetyl-CoA is an important molecule in metabolism, used in many biochemical reactions. Its main function is to convey the carbon atoms within the acetyl group to the citric acid cycle (Krebs cycle) to be oxidized for energy production. The structure of coenzyme A (CoASH or CoA) consists of a β-mercaptoethylamine group linked to the vitamin pantothenic acid through an amide linkage. The acetyl group (indicated in blue in the structural diagram on the right) of acetyl-CoA is linked by a "high energy" thioester bond to the sulfhydryl substituent of the β-mercaptoethylamine group. It is this thioester bond that makes acetyl-CoA one of the "high energy" compounds. Hydrolysis of the thioester bond is exergonic (-31.5 kJ). Acetyl-CoA is produced during breakdown of carbohydrates through glycolysis, as well as by the beta-oxidation of fatty acids. It then enters the citric acid cycle, where the acetyl group is further oxidized to carbon dioxide and water, with the energy thus released captured in the form of 11 ATP and 1 GTP molecules per acetyl group that enters the cycle. |
