What are the biological functions of peptides? What is the function of a peptide

It involves hormonal, nervous, cell growth, and reproductive domains, and its importance lies in the regulation of various systems and cells in the body. The physiological and pharmacological effects of enzymatic peptides are mainly to activate the relevant enzyme system in vivo, promote the permeability of the intermediate metabolic membrane, or affect the synthesis of specific proteins by controlling DNA transcription or translation, and finally produce specific physiological effects or exert their pharmacological effects.

Bioactive peptides: It has the functions of metabolic and physiological regulation, easy digestion and absorption, promoting immunity, regulating hormones, and antibacterial.

Peptide is the form of expression necessary for the human body to maintain life activities, and the form of protein absorbed by the human body is absorbed in the form of small peptides, which can directly enter the cell membrane and bind to the cell membrane to form antibodies. Improve the body's ability to fight viruses.

Super activity, smooth and precise action, extremely high safety, activity diversity, easy absorption, clear mechanism, controllable quality.

The functions of peptides include antihypertensive, antioxidant, cholesterol lowering and other functions. Peptides are mainly divided into medical peptide drugs, peptide antibiotics, vaccines, agricultural antimicrobial peptides, feed peptides, cosmetics for daily chemicals, soybean peptides for food, corn peptides, yeast peptides, and sea cucumber peptides.

From a functional point of view, it can be divided into: antihypertensive peptides, antioxidant peptides, cholesterol-lowering peptides, opioid active peptides, high F-value oligopeptides, food strong taste peptides and so on. Active peptides are closely related to nutrition, hormones, enzyme inhibition, immune regulation, antibacterial, antiviral, and antioxidant. Peptides are broadly divided into:

Peptide drugs and peptide health products.

Traditional peptide drugs are mainly peptide hormones, and the development of peptide drugs in 2011 has developed to various fields of disease prevention and control, especially in the following fields.

Biological peptide is a general term for 20 kinds of natural amino acids in proteins composed of different peptides from dipeptides to complex linear and circular structures, which are multifunctional compounds derived from proteins and have a variety of human metabolism and physiological regulatory functions.

Peptides are bioactive substances involved in a variety of cellular functions in living organisms. Hundreds of peptides have been discovered in living organisms, which are indispensable participants in the body's accomplishment of various complex physiological activities. All cells are capable of synthesizing peptide substances, and their functional activities are also regulated by peptides.

Bioactive peptides (BAP) are peptide compounds that are beneficial to the life activities of biological organisms or have physiological effects, and are a class of polypeptides with a relative molecular weight of less than 6000DA and a variety of biological functions. Bioactive peptides have a variety of human metabolism and physiological regulation functions, easy to digest and absorb, promote immunity, hormone regulation, antibacterial, antiviral, blood pressure, blood lipid and other functions, is the most popular research topic in the international food industry and a functional factor with great development prospects. There are three main ways to artificially synthesize bioactive peptides:

Chemical synthesis, enzymatic synthesis and recombinant DNA technology. The chemical synthesis pathway is mainly solid phase synthesis and liquid phase synthesis, and the disadvantages of chemical synthesis method: racemization and side reactions; Groups in the peptide side chain need to be protected; Excess amount of linking reagent and acyl support is required; Toxic residues from linked reagents affect product quality and the environment.

The enzyme synthesis method has many advantages, such as mild reaction and directionality of the enzyme catalytic position, but there are many reaction by-products and the yield is too low. However, the use of DNA recombinant technology can only synthesize large peptides and proteins, and this method is not suitable for small peptides with nutritional value that are the main needs of human beings.
