近年高考理综卷或单科卷中注重蛋白质结构、功能、鉴定及相关计算的考查,且以选择题为主。有关蛋白质计算题型众多,计算题型中目前尤以柱形图、线环图、线形图等方式呈现蛋白质中的氨基数、羧基数、肽键数、脱水数等数量变化关系的题型倍受青睐,但却很难以把握。现总结归纳如下。一、知识储备1.蛋白质分子量、氨基酸数、肽链数和脱水数的关系
In recent years, college entrance examination science volume or single volume focus on protein structure, function, identification and related calculation of the test, and multiple choice-based. Concerning many types of protein calculation problems, the calculation of the type is currently in column, loop diagram, line graph, etc. protein amino, carboxyl, peptide bond number, the number of dehydration and other changes in the number of questions Favor, but hard to grasp. Now summarized as follows. First, the knowledge reserve 1 protein molecular weight, amino acid number, the number of peptide chain and the relationship between the number of dehydration
