cystein

cystein的音标为[ˈsɪstɪn]，基本翻译是“胱氨酸”。速记技巧可以是：记谐音“丝题恩”，即“丝”代表“胱氨酸”的首字母，而“题恩”则是英文名字。

Cystein这个词的英文词源可以追溯到拉丁语中的“cystis”，意为“膀胱”或“膀胱炎”。这个词在英语中经过了一些变化，包括添加了后缀“in”来表示“含有某种物质的”的意思。

相关单词：

1. cysteine：这是Cystein的常见形式，主要用于生物化学和食品科学中，用于蛋白质的修饰。

2. cystinuria：这是一种疾病，指的是无法正常代谢胱氨酸的肾脏疾病。

3. cystine：这是Cystein的另一个常见形式，通常用于描述含有Cystein的物质。

4. cysticercosis：这是指囊尾蚴病，这是一种由寄生虫引起的疾病，通常在人体内形成囊肿。

5. cystic fibrosis：这是一种遗传性疾病，影响肺部、消化系统和免疫系统。

6. cysteine proteinase inhibitors：这是一种蛋白质抑制剂，用于保护蛋白质免受消化酶的破坏。

7. cystinophilic dyes：这是一种染料，用于染色含有Cystein的蛋白质。

8. cysteine-rich proteins：这是一种富含Cystein的蛋白质，通常在免疫系统中起到重要作用。

9. cysteine-modifying enzymes：这是一种酶，用于修饰Cystein，使其在蛋白质中起到特定的作用。

10. cysteine-based cross-linkers：这是一种基于Cystein的交联剂，用于在生物材料中形成稳定的化学键。

英文小作文：

Cysteine is an essential amino acid that plays a crucial role in the structure and function of proteins. It is found in numerous proteins and contributes to their stability and activity. Cysteine residues can form disulfide bonds, which are important for maintaining protein structure and function. Cysteine is also involved in redox reactions, which are essential for cellular metabolism and signaling. In addition to its role in proteins, cysteine is also found in small peptides and peptides that serve as inhibitors of cysteine proteases, which are crucial enzymes in the digestive system and other cellular processes. Understanding the role of cysteine in biology is essential for understanding how cells function and how diseases develop.
