Simple Definition Of Hydrogen Bond
The short meaning of hydrogen bond is the weak interaction between hydrogen atoms and atoms with large electronegativity and lone pairs of electrons. This effect has a key impact on various fields such as physical state changes and the maintenance of biomolecular structures. In the structure of water, hydrogen bonds connect water molecules, resulting in specific physical properties such as high boiling point and high specific heat capacity. The structural stability of proteins and nucleic acids also depends on hydrogen bonds. The secondary structure of proteins, such as α-helix and β-fold, are all formed by hydrogen bonds; the pairing of base pairs between nucleic acid double strands is also maintained by hydrogen bonds. Although hydrogen bonds are weaker than covalent bonds, they have a huge effect on material properties and life processes.
