"On the Function of Hydrogen Bonding"
All things in the world depend on the maintenance of various forces. Among them, although the hydrogen bond is invisible, it has a crucial impact on all physical properties and chemical properties.
The hydrogen bond is a weak interaction between a hydrogen atom and an atom with a large electronegativity and a small radius (such as fluorine, oxygen, nitrogen, etc.) after being covalently bonded, it is formed with another atom with a large electronegativity. Although this bond is weaker than the covalent bond, it is stronger than the van der Waals force, so it shows its unique efficiency in many material structures and properties.
The property of viewing water, its abnormal high boiling point, depends on the work of hydrogen bonds. The hydrogen bonds between water molecules are criss-crossed, so that in order to change water from liquid to gaseous state, it is necessary to break many hydrogen bonds, which consumes more energy, so the boiling point of water is far higher than that of the same type of molecules. And the specific heat capacity of water is also large, which can maintain its own temperature relatively stable when the ambient temperature changes, and this hydrogen bond is also adjusted in it. When the temperature rises and falls, the formation and breaking of hydrogen bonds absorb or release energy, buffering temperature fluctuations.
In addition, the role of hydrogen bonds in biological systems is also crucial. The secondary structure of proteins, such as alpha-helix and beta-fold, is maintained by hydrogen bonds. In base base complementation, the force of hydrogen bonds is also used to stabilize the DNA double helix structure. The stability of this structure ensures the accurate transmission and storage of genetic information, which is a great contribution to the great cause of the reproduction and continuation of life.
From this point of view, hydrogen bonding is a key factor in the material world and life phenomena. Although its influence is small, it has a wide and deep influence. It is like a silk thread that ties the nature of all things, resulting in this complex and wonderful world.
