Peptide is a compound of alpha-amino acids linked by peptide chains. It is also an intermediate product of protein hydrolysis. Generally, the number of amino acids in a peptide is two to nine. According to the number of amino acids in a peptide, there are many different appellations for a peptide: a compound formed by dehydration and condensation of two amino acids is called a dipeptide. Similarly, there are tripeptide, tetrapeptide, pentapeptide and so on, all the way to a nine-peptide. Polypeptides are usually dehydrated and condensed from 10 to 100 amino acids. Their molecular weight is less than 10,000 Dalton. They can pass through semipermeable membranes and are not precipitated by trichloroacetic acid and ammonium sulfate. In other literatures, the peptide consisting of 2 to 10 amino acids is called oligopeptide (small molecule peptide); the peptide consisting of 10 to 50 amino acids is called polypeptide; the peptide consisting of more than 50 amino acids is called protein, in other words, protein is sometimes called polypeptide.  Peptides, also known as peptides, were discovered in twentieth Century.  Peptides are two kinds of bioactive peptides and synthetic peptides.  Bioactive peptides are highly active, so they are called active peptides.  Only active peptides can have a good effect on human body! But many synthetic peptides are inactive and need to be screened. Only active peptides can be used safely by human body! What are the effects of peptides on human body? Active peptide mainly controls the growth, development, immune regulation and metabolism of human body. It is in a balanced state in the human body. If the active peptide decreases, the human body's function will change significantly. For children, the growth and development of active peptide becomes slow or even stop. For a long time, dwarf will be formed, for adults or adults. Old people, lack of active peptide, their immunity will decline, metabolic disorders, endocrine disorders, resulting in various diseases, such as insomnia, body weight loss or edema. Because active peptides also act on the nervous system, the human body will become slow, the brain is no longer intelligent, more importantly, the decrease of active peptides directly causes the aging of all parts of the human body gradually, leading to various diseases. What are the secretion cycles of human active peptides? In different age periods, the secretion of various active peptides is also very different. According to the secretion volume, people's life can be generally divided into: 1) adequately secreted period (before 25 years of age in youth) this period of balanced endocrine volume, strong immune function, the human body is generally not easy to appear diseases; 2) insufficient secretion period (imbalance period) (30-50 years old adults and middle-aged) In this period, if the secretion of active peptides is insufficient or unbalanced, there will be various related sub-health status and mild disease symptoms (common in people over 40 years old); (3) secretion deficiency period (severe insufficiency period) (middle-aged and old people over 50 years old) this period is serious if the active peptides are seriously insufficient. And serious imbalance, may appear very prominent aging symptoms, or can cause a variety of related diseases (people over 50 years of age are more obvious); 4) secretion termination period (aging period), this period is very short, because the control of human endocrine "commander" active peptide does not secrete or secrete reduced, leading to cell function. Recession leads to organ failure and loss, and finally leads to the end of life. The composition of polypeptide polypeptide is composed of a number of molecules of alpha-amino acid - NH2 and - COOH, which condense and dehydrate each other to form more than 10 long-chain compounds with peptide bonds (-CONH-). It includes a variety of compounds with certain physiological activity in human body, which can be extracted from animal tissues or may be synthesized artificially. Protein is a long chain peptide formed by peptide bonds of various amino acids in a certain order, which is crosslinked by a variety of secondary bonds. Protein has a complex four-level structure. Through hydrolysis of different degrees, the products including polypeptides can be obtained: protein protein pulse peptone. (peptone) > polypeptide to oligopeptide (oligopeptide, long peptide of 2~10 peptide bonds) to amino acids. This also indicates the pathway of protein synthesis. Therefore, synthetic polypeptides can not only be used in biochemical pharmaceutical industry, but also be used to study and elucidate the synthesis pathway and structure of proteins. Many active substances in the human body exist in the form of peptides. It has been found that more than 70% of the body's dry weight is protein, so without peptides, there will be no activity and no life. Peptides involve hormones, nerves, cell growth and reproduction. Their importance lies in regulating the physiological functions of various systems and cells in vivo, activating related enzymes in vivo, promoting the permeability of intermediate metabolic membranes, or controlling DNA transcription or influencing specific protein synthesis, resulting in specific physiological effects. Peptide is an important substance that involves many kinds of cell functions in human body. Peptides can synthesize cells and regulate cell function. Peptides act as neurotransmitters in the body and transmit information. Peptides can be used as a means of transportation in the human body, which transports nutrients, vitamins, biotin, calcium and trace elements beneficial to the human body to cells, organs and tissues of the human body. Peptide is an important physiological regulator of human body. It can comprehensively regulate human physiological function, enhance and exert human physiological activity. It has important biological functions. Peptides are very important for human cell activity, function and life. But because of various factors, modern people lose and lose the peptide in human body, and the ability to synthesize the peptide is greatly weakened. Therefore, the modern human body lacks the peptide, so it is necessary to supplement the synthetic peptide. The complement is the activity, the complement is the activity, and the complement is the supplement.
