2, the role of plant peptides:
Polypeptide plays a very important and irreplaceable role in regulating human body, which involves almost all physiological activities of human body. Such as: nerves, digestion, absorption, metabolism, circulation, growth, reproduction, endocrine and so on. At present, many researches on peptides have been applied to the development of medicine and health food. Insulin, which we are familiar with, is a polypeptide, and oxytocin and vasopressin are polypeptide hormones. In a high-tempo, high-tension society, the number of people with abnormal sleep is expanding, and hypnotic peptide will be the best choice because it has no side effects. Other effective drugs for treating diabetes, gastric ulcer, pancreatitis, dwarfism and gallbladder contraction are peptides. For human immune system, peptides are more important and direct, such as mannan peptide, thymosin peptide and albumin polypeptide. It can quickly activate macrophages and T cells, thus improving human cellular immunity and preventing infection caused by coronavirus.
3. Bioactive peptides are the general name of 20 natural amino acids in protein, which have different compositions and arrangements, ranging from dipeptide to complex linear and cyclic structures. They are multifunctional compounds from protein. Active peptides have a variety of human metabolism and physiological regulation functions, are easy to digest and absorb, and have the functions of promoting immunity, regulating hormones, resisting bacteria and viruses, lowering blood pressure and blood lipid, and are extremely safe to eat. They are the hottest research topics and functional factors with great development prospects in the international food industry.
