The basic unit constituting a protein is an amino acid, and the amino acid forms a peptide chain by dehydration condensation. A biological macromolecule consisting of one or more polypeptide chains, each of which has between twenty and hundreds of amino acid residues; various amino acid residues are arranged in a certain order. The organelle that produces the protein is the ribosome. Protein is the material basis of life. Without protein, there is no life. Therefore, it is a substance closely related to life and various forms of life activities.
Protein is involved in every cell and all important components in the body. Protein accounts for 16.3% of the body's weight, that is, an adult weighing 60 kg has about 9.8 kg of protein in the body. There are many kinds of proteins in the human body, and their properties and functions are different. However, they are composed of more than 20 kinds of amino acids in different proportions, and are continuously metabolized and renewed in the body. The protein to be ingested is digested into amino acids in the body. After absorption, it is mainly used in the body to recombine adult protein in a certain proportion. At the same time, the new protein is continuously metabolized and decomposed, and is constantly in dynamic equilibrium. Therefore, the quality and quantity of food protein, the proportion of various amino acids, is related to the amount of protein synthesis in the human body, especially the growth and development of adolescents, the prenatal and postnatal care of pregnant women, the longevity of the elderly, and the amount of protein in the diet. close relationship.
Acids are biological macromolecules that are polymerized from nucleotides. The deoxyribonucleotides constituting DNA are mainly dAMP, dGMP, dCMP and dTMP, and the ribonucleotides constituting RNA are mainly AMP, GMP, CMP and UMP. A nucleotide in a nucleic acid forms a linear molecule having no branching structure by a 3', 5' phosphodiester bond. The nucleic acid strand is directional, with two ends being the 5' end and the 3' end, respectively. The 5' end contains a phosphate group and the 3' end contains a hydroxyl group. The 3' hydroxyl group of the former nucleotide in the nucleic acid strand and the 5' phosphate of the next nucleotide form a 3', 5' phosphodiester bond, so the nucleotide in the nucleic acid is called a nucleotide residue. . A nucleic acid consisting of less than 50 nucleotide residues is typically referred to as an oligonucleotide, and a greater than 50 nucleotide residue is referred to as a polynucleotide.
