I believe we have all heard of amino acid mask, peptide oral liquid, protein powder and other products, but many of us do not understand what kind of relationship there is between them. What kind of role do you have? In order to understand these problems, we must first understand the relationship among amino acids, polypeptide synthesis and proteins. Amino acids are the basic units of proteins, and peptides are intermediate substances between amino acids and proteins. The molecule of amino acid is the smallest and the protein is the largest. Amino acids make up peptides, peptides form proteins. Today we first understand the main differences between peptides and proteins, and the differences between peptides and proteins lie in four major aspects. First, peptides are easy to absorb and have no antigenicity. Proteins belong to macromolecules and are not easy to absorb. They must be decomposed into peptides or amino acids before they can be absorbed. Peptides can be absorbed into the circulatory system and absorbed directly into cells to participate in protein synthesis, and no waste and metabolites will be produced in this process, and more importantly, the absorption rate of peptides is 20 times that of ordinary proteins. Second, the biological activity of peptides is very high and the range of action is wide.
The biological activity of small molecular peptides is higher, and it can also play its unique physiological function in extremely small cases. Bioactive peptides can transmit physiological information and regulate physiological functions, and maintain the normal physiological activities of human body. Active peptides play an indispensable role in the cells, organs and tissues of the body. Third, the structure of peptides is easy to synthesize. Because the structure of small molecular peptides is much simpler than that of proteins, the structure of small molecular active peptides is easy to synthesize and the cost of artificial synthesis is low. These characteristics provide a broad prospect for the development of polypeptide drugs. Fourth, peptides do not cause excess nutrition. We all know that excessive intake of protein will have certain side effects, because there are many decomposition products of protein in the human body, in which ammonia, ketoacid and urea will have side effects on the human body, which will not only increase the burden on the liver, but also easily cause dyspepsia to affect renal function. And eating too much protein increases the risk of cancer, and eating too much animal proteins such as eggs, milk and meat can also cause heart disease. However, the intake of peptides not only does not cause excess nutrition, but also can regulate the nutritional balance of the human body.
