A hydrogen bond is a partially electrostatic attraction that works between a hydrogen atom (i.e. bound to a more electronegative atom or group of atoms) and an adjacent atom with a lone pair of electrons.
Hydrogen Bond Definition. A hydrogen bond is an attractive dipole-dipole interaction between a partially positive charged hydrogen atom in one molecule and a partially negative charged atom in the same or different molecule. As the name suggests, a hydrogen bond always involves a hydrogen atom, but the other atom can be any more electronegative ...
A hydrogen bond is weaker than an ionic bond or a covalent bond, but stronger than van der Waals forces. Hydrogen bonds play an important role in biochemistry and produce many of the unique properties of water.
Hydrogen bonds are strong intermolecular forces created when a hydrogen atom bonded to an electronegative atom approaches a nearby electronegative atom. Greater electronegativity of the hydrogen bond acceptor will lead to an increase in hydrogen-bond strength.
Hydrogen bonding, interaction involving a hydrogen atom located between a pair of other atoms having a high affinity for electrons; such a bond is weaker than an ionic bond or covalent bond but stronger than van der Waals forces.
Hydrogen bonds are critical non-covalent bonds essential for the structural integrity and function of biological molecules such as DNA and proteins. They facilitate proper protein folding, stability, and specific ligand interactions, such as antigen-antibody binding.
Hydrogen bonds are common in biology both within and between all types of biomolecules. Hydrogen bonds are also critical interactions between biomolecules and their solvent, water. It is common, as seen in the figure below, to represent hydrogen bonds in figures with dashed lines.
The force of attraction, shown here as a dotted line, is called a hydrogen bond. Each water molecule is hydrogen bonded to four others. The hydrogen bonds that form between water molecules account for some of the essential — and unique — properties of water.
A hydrogen bond is a type of weak chemical bond that occurs when a hydrogen atom covalently bonded to a highly electronegative atom, like oxygen or nitrogen, experiences an attraction to another electronegative atom.
Definition. A hydrogen bond is a weak, attractive force that occurs between a hydrogen atom covalently bonded to a more electronegative atom and another electronegative atom. This type of bond is crucial for the structure and properties of biological macromolecules, influencing their shape, stability, and interactions.
