"Intermolecular forces of hydrogen chains"
Between heaven and earth, things have their own properties, and the relationship between them is subtle. When it comes to the intermolecular forces of hydrogen chains, this is the key to the relationship between physical properties.
The intermolecular forces of hydrogen chains originate from the electrostatic attraction between hydrogen atoms and atoms with large electronegativity and small radius (such as fluorine, oxygen, nitrogen, etc.). Although this force is not as strong as chemical bonds, it has a far-reaching impact on the properties of many substances.
Looking at liquid water, water molecules attract each other due to the forces between hydrogen chain molecules, which makes water have a higher boiling point. If it were not for this force, the boiling point of water would be much lower than it is today, so the state of rivers, lakes and seas in the world would be very different from today. And the specific heat capacity of water is also quite high due to the action of hydrogen chains, which can buffer and adjust when the ambient temperature changes, maintaining ecological stability.
In biological systems, the secondary structure of proteins, such as α-helix and β-fold, depends on the intermolecular force of hydrogen chains to maintain their stability. The stability of this structure is related to the normal development of protein functions. If the hydrogen chain is damaged, the structure of the protein will change, its function will also be lost, and life activities will be hindered.
In nucleic acids, the pairing of base pairs also relies on the intermolecular force of the hydrogen chain. Adenine and thymine, guanine and cytosine, pair by pair, construct the orderly transmission of genetic information. Without this force, the inheritance of the genetic code will be chaotic and disordered, and the continuation of life will become illusory.
The intermolecular force of the hydrogen chain, although small but heavy, plays an indispensable role in material form and life activities, and is the key to exploring the mystery of physical nature.
