高中化学教材第二册讲到氨基酸是构成蛋白质的“基石”以及蛋白质是由α—氨基酸通过肽键构成的高分子化合物。但是教材里并没有配合实验来说明。现介绍一种实验方法,通过蛋白质水解液的纸上层析实验来说明氨基酸是构成蛋白质的“基石”。
The second volume of the high school chemistry textbook says that amino acids constitute the “base stone” of proteins and that proteins are alpha-amino acids that are composed of peptide bonds. However, the teaching materials did not match the experiment. An experimental method is now introduced to demonstrate that amino acids are the “basestones” of proteins through paper chromatography experiments on protein hydrolysates.
