What Is A Hydrogen Bond Biology
On the composition of the hydrogen bond
The composition of the male matter, between the tiny and the hydrogen bond, the most heavy and mysterious.
Hydrogen, the light element is also, when it is connected with atoms with strong electronegativity, such as fluorine, oxygen, and nitrogen, by covalent bonds, its electron cloud is concentrated on the side of the strong electronegative atom, causing the hydrogen atom to naked its positively charged nucleus, which then has strong electrophilicity. At this time, if there is an atom with strong electronegativity and a lone pair of electrons in the neighbor position, the two are introduced into each other, and the hydrogen bond is formed.
In the field of biology, the work of hydrogen bonds is innumerable. The structure of proteins depends on hydrogen bonds to maintain their secondary and tertiary states. In the alpha-helix, the polypeptide chain is wound into a regular form by hydrogen bonds; between the beta-folds, it also maintains the integrity of its sheets by hydrogen bonds. This regular shape is the basis for the function of proteins, and the functions of catalysis, transportation, and defense all depend on it.
In nucleic acids, bases are paired, and hydrogen bonds are bridges. Adenine and thymine, guanine and cytosine, are linked by hydrogen bonds, and the double helix can be formed. The storage and transmission of genetic information is orderly. Without hydrogen bonds, the order of genes is chaotic, and life is at risk.
Water, the source of life, the nature of hydrogen bonds in water, has a huge impact. Hydrogen bonds increase the attractive force between water molecules. The boiling point and melting point of water are different from common sense, and the liquid state is stable at room temperature. And the high specific heat and high heat of vaporization of water are all the forces of hydrogen bonds. The constant temperature of biological bodies and the smooth biochemical reactions in the body, water is the most powerful because of hydrogen bonds.
In short, although hydrogen bonds are small, they are the key to the structure, energy and derivation of living things. Understanding the principle of hydrogen bonds is a corner of the mystery of life.
