摘要   实验研究中常常观察到钠离子与一些多肽或蛋白质有较强的非共价键结合能力,这种非共价键相互作用可能与生物的一些功能和活性有关.为了进一步了解这一结合作用,我们应用电喷雾质谱研究了常见的20种氨基酸与钠离子在溶液中的非共价键相互作用.实验研究中发现脯氨酸和苯丙胺酸与钠离子有较强的非共价键结合能力.…… Non - covalent interaction between amino acids and sodium ion in solution were investigated by ESI - MS in this report. It was discovered that proline and phenylalamine of 20 kind amino acids have a strong non - covalent binding force for sodium ion.
