氢键

液态水模拟图。照片中心的分子引出的的蓝色虚线代表氢键。
Ejemplo de enlace de hidrógeno intermolecular en un complejo dimérico autoensamblado molecular reportado por Meijer y colaboradores.[1]
Ejemplos de grupos donantes de enlace de hidrógeno, y grupos aceptores de enlace de hidrógeno.

氢键是分子间作用力的一种,是一种永久偶极之间的作用力,氢键发生在已经以共价键与其它原子键合的氢原子与另一个原子之间(X-H…Y),通常发生氢键作用的氢原子两边的原子(X、Y)都是电负性较强的原子。氢键既可以是分子间氢键,也可以是分子内的。其键能最大约为200kJ/mol,一般为5-30kJ/mol,比一般的共价键、离子键和金属键键能要小,但强于静电引力。

氢键对于生物高分子具有尤其重要的意义,它是蛋白质和核酸的二、三和四级结构得以稳定的部分原因。

Examples of hydrogen bond donating (donors) and hydrogen bond accepting groups (acceptors)

A hydrogen bond is the electrostatic attraction between polar groups that occurs when a hydrogen (H) atom bound to a highly electronegative atom such as nitrogen (N), oxygen (O) or fluorine (F) experiences attraction to some other nearby highly electronegative atom.
