dextrorotation

dextrorotation的音标为[dɪk"strɔːrəʊˌteɪʃən] ，基本翻译为“顺时针方向旋转”，速记技巧为：顺=d，针=k，旋=r，方=o，向=t。

Dextrorotation是一个英语单词，意思是顺时针旋转。这个词来源于拉丁语“dexter”（意为右手）和“rotare”（意为旋转）。

变化形式：在化学中，dextrorotation的形式通常是指分子的手性旋转。它可以通过改变取代基的位置或构型来改变分子的旋转方向。

相关单词：

(D)extro（缩写）: 意为“向外，出”的意思，常用于描述与dextrorotation相反的过程。

(R)-isomer（R-异构体）: 意为“右旋异构体”，用于描述具有特定旋光性的化合物。

(S)-isomer（S-异构体）: 意为“左旋异构体”，用于描述具有相反旋光性的化合物。

(+)Enantiomer（正旋体）: 意为“（+）单一镜象的化合物”，用于描述具有相同旋光性的化合物。

(-)Enantiomer（负旋体）: 意为“（-）单一镜象的化合物”，用于描述具有相反旋光性的化合物。

Chiral center（手性中心）: 意为“手性中心”，用于描述具有不对称碳原子的化合物，这些碳原子可以导致分子的手性旋转。

Rotation number（旋转数）: 用于描述分子的旋转方向和程度的概念。

Dextrin（右旋糖）: 一种具有特定旋光性的多糖，常用于食品和药品中。

Dextrification（右旋化）: 用于描述向顺时针方向旋转的过程。

以上单词都与dextrorotation这个概念密切相关，它们描述了与手性旋转相关的不同方面和概念。

英文小作文：

Dextrorotation is an important property of sugars, which determines their optical activity and solubility in water. Dextrins are complex carbohydrates commonly found in fruits and vegetables, which are produced by the hydrolysis of starch. Dextrins are dextrorotatory in nature and are used in various industries as sweeteners, excipients, and food additives. Dextrins are also used in the production of biodegradable polymers, which are used in various applications such as packaging materials and medical devices. In addition, dextrins are also used in the production of pharmaceuticals, where they act as excipients to improve the solubility and stability of drugs. Understanding the properties of dextrins and their isomers is crucial for the development of new products and processes in various industries.
