acetyl-CoA的音标是["æsɪtɪl kəʊəʊ ɪə],翻译为乙酰辅酶A。速记技巧是记住其结构特征,即一个乙酰基(CH3-C=O)连接一个辅酶A(CoA)。
Acetyl-CoA的英文词源是来自希腊语和拉丁语,其中acetyl来自于acetic(乙酸的)和co-(共同)的组合,而CoA则来自于英语中的辅酶A(coenzyme A)。
变化形式:酯基的乙酰化(Acetylation)是生物化学中常见的一种修饰,可以发生在许多蛋白质、核酸和糖类等生物大分子上。
相关单词:Acetylcholine乙酰胆碱,一种神经递质,在神经肌肉接合处释放,参与肌肉运动;Acetylator乙酰化酶是一种基因,编码能够催化蛋白质的乙酰化反应的酶。此外,Acetyl-CoA还可以衍生出许多其他单词,如乙酰辅酶A(Acetyl CoA),它是生物体内一种重要的能量中间体,参与许多代谢途径。
总的来说,Acetyl-CoA在生物化学中扮演着重要的角色,是许多代谢途径的起点,也是许多生物化学反应的中间产物。

英文小作文:
The chemical compound acetyl-CoA plays a vital role in cellular metabolism, acting as a central intermediate in numerous biochemical reactions. It is produced through a series of complex reactions, starting from glucose, pyruvate, and other substrates, and it serves as a precursor for the synthesis of fatty acids, cholesterol, and other biomolecules. Acetyl-CoA is also involved in energy production through its conversion to ATP, the universal energy currency of the cell.
Moreover, acetyl-CoA is central to the citric acid cycle, a series of chemical reactions that generate energy and regulate cellular metabolism. Through this cycle, cells are able to convert nutrients into energy and other essential biomolecules, ensuring their survival and growth. Understanding the role of acetyl-CoA in cellular metabolism is crucial for understanding human health and disease, as well as for developing effective therapeutic strategies.
