摘要：

蛋白质是生命体内一类具有重要生物活性的有机分子；对蛋白质进行合成与修饰是探索生命奥秘的重要途径。第54届国际化学奥林匹克试题第7题以蛋白质的合成与修饰为主要内容，考查了酰胺键的构建方法、多肽链的连接策略和蛋白质的修饰手段。

关键词: 蛋白质合成, 蛋白质修饰, 酰胺键, 肽

Abstract:

Proteins are a class of organic molecules with important biological activities in life; the synthesis and modification of proteins is an important way to explore the mysteries of life. The problem 7 of the 54th International Chemistry Olympiad mainly focuses on the synthesis and modification of proteins, investigated the construction method of amide bond, the connection strategy of peptides and at last the modification method of protein.

Key words: Synthesis of proteins, Modification of proteins, Amide bond, Peptides
