Protein Building Blocks and Folding

Proteins are built from amino acids linked by peptide bonds. Long chains of amino acids are often called polypeptides, and the terms proteins and polypeptides are sometimes used the same way. In this context, polypeptides with a molecular weight below 10,000 daltons are called polypeptides, while proteins have a higher molec...

蛋白质是由氨基酸组成的链，氨基酸是一类含有氨基和羧基以及连接在中心碳原子上的不同侧链（用R表示）的化合物。

氨基酸通过共价肽键连接，沿其核心的重复原子序列称为多肽骨架。

该序列从N端开始，带有一个游离的氨基（NH₃
