Hydrogen Bond Definition Simple
Hydrogen, one of the elements, is often involved in the appearance of hydrogen bonds in chemistry. The hydrogen bond is a weak bond between molecules or atomic groups, where hydrogen is connected to atoms with large electronegativity and small radius (such as fluorine, oxygen, nitrogen, etc.) by electrostatic action. Although this bond is weaker than the covalent bond, it has a huge impact on the properties of matter.
Looking at the state of water, it is a liquid at room temperature, which depends on the force of hydrogen bonds. Hydrogen is connected to oxygen in water molecules, and between adjacent water molecules, hydrogen and oxygen are connected by hydrogen bonds, causing water to have a rather high boiling point, which is different from common sense. If it were not for hydrogen bonds, the boiling point of water would be much lower than the current temperature, and the life of life would be greatly changed.
In biological macromolecules, such as proteins and nucleic acids, hydrogen bonds are also important. The secondary structure of proteins, alpha-helix and beta-fold, are all formed by hydrogen bonds. The base pairs of nucleic acids are also paired by hydrogen bonds to stabilize their structure and pass on their genetic information.
In short, although hydrogen bonds are small, they have key effects in the fields of chemistry and biology. They affect the state and properties of matter and are a mystery that cannot be ignored in the microscopic world.
