Many active substances in the human body exist in the form of peptides. Peptide involves the human body's hormones, nerves, cell growth and reproductive fields. The importance is to regulate the physiological functions of various systems and cells in the body, activate the enzyme system in the body, promote the permeability of intermediate metabolic membranes, or use control DNA transcription or transcription or It affects specific protein synthesis and eventually produces specific physiological effects. Peptide is an important substance involving a variety of cell function in the human body. Peptide can synthesize cells and regulate cell functional activity. Peptides are used as neurotransmitters to pass information. Peptides can be used as transportation tools, and the various nutrients that the human body eats and various vitamins, biomas, calcium and trace elements that are beneficial to the human body to various cells, organs and tissues in the human body. Peptide is an important physiological regulator of the human body. It can comprehensively regulate the physiological function of the human body, enhance and exert the physiological activity of the human body. It has important biological functions. Peptide is too important to have cell activity, functional activity, and life. However, due to various factors, the peptide in the human body is lost and the ability of synthetic peptide has greatly weakened. Therefore, the lack of peptides in modern human body must supplement artificial synthetic peptide.
