蛋白质是生命活动中极为重要的物质之一,虽然这一知识点包括学生实验,但其独特的魅力和丰富的知识内涵,经常受到命题者的关注,特别近年的化学高考试题中,就出现了许多与氨基酸和蛋白质有关的好题.现分类解析如下.一、考查氨基酸分子的结构通式例1某天然蛋白质充分水解后,能分离出有机物R,R可与等物质的量的KOH或盐酸完全反应.3.75 g R可与50 mL、1mol/L的NaOH完全中和,则R的结构简式为()
Although protein is one of the most important substances in life activities, although this point of knowledge includes students’ experiments, its unique charm and abundant knowledge connotations are often paid attention to by proponents. In particular, in recent chemistry entrance examinations, A lot of amino acids and protein-related issues now classified analysis is as follows: First, examine the structure of amino acid molecules General Example 1 A natural protein hydrolysis, can separate the organic matter R, R and other substances can be the amount of KOH or hydrochloric acid Complete reaction .3.75 g R with 50 mL, 1mol / L NaOH completely neutralized, then the structure of R ()
