Hydrogen Bonding Requirements
On the need for hydrogen bonding
The structure of all things, there are many hydrogen bonds. To understand the truth, we should study the need for hydrogen bonds in detail.
The formation of hydrogen bonds must have its own requirements. Hydrogen needs to be connected to atoms with strong electronegativity, such as fluorine, oxygen, and nitrogen. These atoms have a very attractive force on electrons, and the electron cloud caused by hydrogen is biased to the other side, so hydrogen is partially positively charged.
And there needs to be another atom with strong electronegativity and lone pair electrons nearby. The lone pair electrons of this atom can attract each other with positively charged hydrogen, and hydrogen bonds are formed. Without one of the two, hydrogen bonds cannot exist.
Looking at the changes in the state of matter, the need for hydrogen bonds is obvious. The boiling point of water is different from the common sense, covering the work of hydrogen bonds between water molecules. If there is no need for this hydrogen bond, the state of water will change, how can it be seen today?
In the field of biochemistry, the conformation of proteins and nucleic acids depends on hydrogen bonds to stabilize. The secondary structure of proteins, α-helix and β-folding, are all formed by hydrogen bonds. The base pairing of nucleic acids is also caused by hydrogen bonds. If the need for hydrogen bonds is not harmonious, the delicate structure of living things may be difficult to maintain.
From this perspective, the need for hydrogen bonds is the key to the structure, properties and biological system of matter. To understand this need, we can see the mystery of changes in the microscopic world and explore the secret of the operation of all things.
