Describe Hydrogen Bonds
Hydrogen is the light and pure gas. Its bonding with matter is called hydrogen bonding.
Hydrogen bonding is not a genus of strong ionic bonds and covalent bonds. Because hydrogen atoms are related to atoms with strong electronegativity (such as fluorine, oxygen, nitrogen, etc.), the only electron of hydrogen is biased to its strong electronegativity atoms, causing hydrogen nuclei to be slightly exposed and positive. And this positive hydrogen can attract atoms with strong electronegativity and lone pairs of electrons in other molecules with a weak force, which is hydrogen bonding.
The shape of hydrogen bonds affects the properties of matter. In water, due to the existence of hydrogen bonds, the boiling point and melting point of water are higher than common sense. If there is no hydrogen bond, water at room temperature or as gas, it is difficult to become the source of life. In the genus of proteins and nucleic acids, hydrogen bonds maintain their structure. The secondary structure of proteins, such as alpha-helix and beta-folding, depends on hydrogen bonds to stabilize; the base pairing of nucleic acids also relies on hydrogen bonds to transmit genetic information.
From the perspective, although hydrogen bonds are not strong, they are of great significance in the state of all things and the process of biochemistry and cannot be ignored.
