在蛋白质分子教学过程中,学生时常会发现氨基酸、氨基、羧基等因素间的关系错综复杂,面对此类计算问题,他们往往无从下手。这里我总结几个规律,以帮助大家解决此类问题。一、氨基酸数与肽链数、肽键数、脱水数的关系n个氨基酸综合成一条肽链时,形成(n-1)肽键,由于每形成一个肽键都要脱去1分子水,所以脱水数也为(n-1),即:脱水数=肽键数=氨基酸数-1,那么当n个氨基酸形成m条肽链时,它们四种关系 In the process of protein molecular teaching, students often find the relationship between amino acids, amino, carboxyl and other factors complicated, in the face of such computational problems, they often can not start. Here I summarize a few rules to help you solve such problems. First, the number of amino acids and the number of peptide chains, the number of peptide bonds, the relationship between the number of dehydration Synthesis of n amino acids into a peptide chain, the formation of (n-1) peptide bonds, since each formed a peptide bond to take off a molecule of water, Therefore, the number of dehydration is also (n-1), that is, the number of dehydrations = the number of peptide bonds = the number of amino acids - 1, and when n amino acids form m peptide chains,
