本文综述了氨基酸分子内氢键种类和数目对分子构象稳定性和光电离解离动力学的各种效应:得出分子内含有N…H—O和C O…H—O氢键的构象具有较高的热力学稳定性;N…H—O氢键导致分子第一电离能数值的增加,同时可以导致电离过程中的质子转移以及后续二氧化碳释放的解离过程;氨基酸分子正离子的稳定性或碳碳化学键断裂解离动力学也不尽相同,丝氨酸分子在电离阈值附近解离过程中表现出奇特的立体效应。 In this paper, the effects of the type and number of intramolecular hydrogen bonds in amino acids on the conformational stability and photodissociation kinetics of amino acids were summarized. The conformations with intramolecular N · H-O and CO ... H-O hydrogen bonds were found to have higher H-O hydrogen bond leads to the increase of the first ionization energy of the molecule, and at the same time it can lead to the proton transfer in the ionization process and the dissociation of the subsequent carbon dioxide release; the stability of the positive ion of the amino acid molecule or the carbon-carbon The dissociation kinetics of chemical bond cleavage are also different, and the serine molecules show unique stereoscopic effect in the process of dissociation near the ionization threshold.
