denaturant

denaturant的音标为[dɪ"nætʃər(ə)nt]，基本翻译为“变性剂”，速记技巧为“denat=变性”。

Denaturant这个词的词源可以追溯到拉丁语和化学领域。它指的是一种能够改变或破坏物质原有性质的物质，通常用于化学实验中，使蛋白质等生物分子变性。

变化形式：在英语中，denaturant通常以名词的形式出现，没有明显的变化形式。

相关单词：

1. denaturing：这个词与denaturant相关，指的是使蛋白质等生物分子变性的过程。它可以作为动词使用。例如，“The protein sample was denatured in the denaturant solution.”（蛋白质样品在变性溶液中被破坏。）

2. deproteinize：这个词也与蛋白质有关，指的是通过使用denaturant等物质使蛋白质变性或破坏的过程。例如，“The sample was deproteinized for further analysis.”（样品被破坏以供进一步分析。）

3. denaturation：这个词也是与变性相关的，指的是蛋白质等生物分子在受到外界因素影响而发生结构改变的过程。例如，“The protein underwent denaturation during the experiment.”（蛋白质在实验过程中发生了变性。）

例句：The denaturant solution was added to the sample, causing the proteins to denature.（将变性溶液添加到样品中，导致蛋白质变性。）

以上这些单词都与denaturant有着密切的联系，并且都涉及到生物分子变性的过程。这些单词在生物化学实验和研究中经常被使用。

Denaturants and Protein Denaturation

Denaturants are chemical agents that can unfold proteins, making them more accessible for study and analysis. Chemical denaturants such as urea and detergents are commonly used to study protein structure and function, as they can effectively disrupt the native conformation of proteins and expose their tertiary and quaternary structures. In addition, thermal denaturation, where proteins undergo conformational changes upon exposure to high temperatures, can also be used to study protein stability and folding mechanisms. Understanding the denaturant effect on proteins is crucial for biotechnology research and industrial applications, as it can provide valuable insights into protein function and interactions with other molecules in the cell.
