What does nucleotide mean?

Nucleotide is the basic unit of ribonucleic acid and deoxyribonucleic acid and the precursor of nucleic acid synthesis in vivo. Nucleotide is a kind of compound composed of purine base or pyrimidine base, ribose or deoxyribose and phosphoric acid. Pentose and organic base synthesize nucleoside, nucleoside and phosphoric acid synthesize nucleotide, and four nucleotides form nucleic acid. Nucleotides are mainly involved in the formation of nucleic acids, and many single nucleotides also have many important biological functions.

In organisms, nucleotides can be synthesized from some simple compounds. These synthetic raw materials include aspartic acid, glycine, glutamine, one carbon unit and CO2. Nucleotide is the basic structural unit of nucleic acid, and nucleotides in human body are mainly synthesized by cells themselves. Nucleotides are widely distributed in the body.

Cells mainly exist in the form of 5'- nucleotides. The concentration of ribonucleotides in cells far exceeds that of deoxynucleotides. The content of various nucleotides in different types of cells is very different, and the content of various nucleotides in the same cell is also different, and the total number of nucleotides has not changed much.

Extended data:

There are five kinds of 1. nucleotides: CMP (cytosine nucleotide), UMP (uracil nucleotide), AMP (adenine nucleotide), GMP (guanine nucleotide) and IMP (hypoxanthine nucleotide). Each nucleotide has its own unique function. Just as a successful department needs different members and complementary advantages, the formation of a baby's own resistance also needs the coordination of five different nucleotides.

Second, the role of nucleotides: nucleotides play an important role in intestinal nutrition and can promote the growth, development and repair of intestinal cells. The human body actively synthesizes nucleotides mainly in the liver, which requires a lot of energy. The remedy is to form new nucleotides from nucleotide fragments or foreign nucleotides, which requires less energy, although the liver has the ability to synthesize nucleotides from scratch.

However, once immune stress occurs in the body, which leads to the activation and proliferation of T lymphocytes, it will lead to a rapid increase in nucleotide synthesis, and the demand for preconditions involved in energy metabolism and nucleotide synthesis will also increase accordingly. Moreover, the energy required to supplement exogenous nucleotides is less than that required for de novo synthesis, so it is quite necessary to supplement exogenous nucleotides.

Nucleotide has a certain regulatory effect on many basic biological processes. The basic components of all living things play a leading role in the growth, development, reproduction and inheritance of living things. For example, milk powder can maintain the normal function of baby's gastrointestinal tract, reduce diarrhea and constipation, improve immunity and reduce illness.
