蛋白质中氨基酸数、氨基数、羧基数、肽链数、肽键数、脱水数、分子量等各因素之间的数量关系,蛋白质中氨基酸数与核酸中碱基数之间的数量关系,是高考的必考点,因此,对蛋白质中有关数量的计算题应重点关注。一、原理1.形成的肽键数=失去的水分子数;2.m个氨基酸分子形成一个由n The number of amino acids in a protein, the number of amino groups, the number of carboxyl groups, the number of peptide chains, the number of peptide bonds, the number of dehydration, and the molecular weight, and the quantitative relationship between the number of amino acids in a protein and the number of bases in a nucleic acid are the entrance examinations. The test must be focused on the calculation of the number of proteins in question. 1. Principle 1. Number of peptide bonds formed = number of lost water molecules; 2.m amino acid molecules form one by n
