hydrogen bond

hydrogen bond
hydrogen bond n an electrostatic attraction between a hydrogen atom in one polar molecule (as of water) and a small electronegative atom (as of oxygen, nitrogen, or fluorine) in usu. another molecule of the same or a different polar substance
hydrogen bonding n

* * *

a weak electrostatic bond formed by linking a hydrogen atom between two electronegative atoms (e.g. nitrogen or oxygen). The large number of hydrogen bonds in proteins and nucleic acids are responsible for maintaining the stable molecular structure of these compounds.

* * *

a relatively weak, primarily electrostatic, bond between a hydrogen atom bound to a highly electronegative element (such as oxygen or nitrogen) in a given molecule, or part of a molecule, and a second highly electronegative atom in another molecule or in a different part of the same molecule. The hydrogen bond is generally represented by three dots, e.g., XH···Y, where X and Y are electronegative atoms.
