enantiomer

enantiomer的音标是[ɪˈnæniəmər]，意思是手性异构体、对映体。

速记技巧：谐音记法：“恩娜一莫儿”

基本翻译：对映体、异构体。

Enantiomer 的词源是希腊语单词 "enantios"，意为“单侧的”或“倾斜的”。这个词后来被用来描述具有镜像对称性的分子，即手性分子的一侧与另一侧在视觉上对称，但并无真正的对应关系。

变化形式：在英语中，enantiomer 的词形一般不变。

相关单词：

1. Diastereomer (同义词，指具有手性结构的化合物)

2. Racemate (来自拉丁语，意为“两种相反的东西”，指两种对映异构体的混合物)

3. Chiral (来自希腊语，意为“有手性的”)

4. Optical isomer (光学异构体，指具有镜像对称性的分子)

5. Enantiomerize (动词形式，意为“使成对映体”)

6. Enantiomerization (名词形式，意为“对映体的形成”)

7. Enantiomerically enriched (意为“手性富集的”)

8. Enantiomerically pure (手性纯的)

9. Enantiomerism (手性，指具有手性的分子或化合物)

10. Chiroisomerism (光学异构，指具有光学活性的分子或化合物)

以上单词都与手性分子及其相关概念有关，描述了手性分子的性质、合成、纯化以及与非手性分子的区别。

1. enantiomerically enriched

2. enantiomerically pure

3. enantiomerically pure substance

4. enantiomerically resolved

6. Enantiomerically pure compounds are used in the food industry for the production of food additives and sweeteners. (在食品工业中，手性纯化合物用于生产食品添加剂和甜味剂。)

7. The enantiomers of a drug should be separated before use to avoid side effects and improve efficacy. (药物的手性异构体在使用前应该分离，以避免副作用并提高疗效。)

英文小作文：

Enantiomers are two mirror-image forms of the same chemical substance, which have identical chemical properties but different physical properties due to their spatial arrangement. Enantiomers are important in chemistry and pharmaceutical research because they can have different pharmacological effects and side effects when taken orally or injected into the body. Therefore, it is important to separate and use enantiomers carefully to ensure effective treatment and minimal side effects.

In the pharmaceutical industry, enantiomerically pure substances are used to produce drugs with fewer side effects because they can be more easily metabolized by the body and have fewer interactions with other substances in the body. In the food industry, enantiomerically pure compounds are used to produce food additives and sweeteners that are safe and effective for human consumption.

In conclusion, enantiomers are an important aspect of chemistry and pharmaceutical research, and understanding their properties and uses is crucial for ensuring safe and effective treatment of diseases and ensuring the safety of food and other substances consumed by humans.
