Chronic diseases have become the number one threat to human health.
In 2017, the "healthy China 2030" planning outline issued by the State Council listed the health industry as a new economic growth point. The guiding opinions on promoting the healthy development of the food industry jointly issued by the national development and Reform Commission and the Ministry of industry and information technology also clearly pointed out that it is necessary to "vigorously support the development of health care and health food such as bioactive peptides" during the 13th Five Year Plan period. Therefore, peptide functional food has occupied an important market position in the health industry.
Peptide is a kind of amphoteric compound, which contains carboxyl group and amino group. The amino group of one amino acid and the carboxyl group of another amino acid can be condensed into peptide. The amide group formed is called peptide bond in protein chemistry. Amino acids have the smallest molecule and the largest protein. Two or more amino acids dehydrate and condense to form several peptide bonds to form a peptide. Multiple peptides can be folded to form a protein molecule.
Characteristics of peptides
Compared with other factors, it has many advantages, such as:
Easy to absorb: the absorbability of oligopeptide is better than that of intact protein;
Good processability: good solubility and stability, low viscosity;
Low sensitization: suitable for allergic constitution;
Low osmotic pressure: reduce the possibility of diarrhea and vomiting.
Based on this, functional peptides have become the bioactive substances which are highly respected and given great attention and praise in the field of modern life science.
Health effects of peptides on human body
Inhibition - inhibit cell degeneration and enhance human immunity.
Activation - activate cell activity and effectively remove harmful free radicals.
Repair - repair the degenerative cells of human body and improve cell metabolism.
Promote - to promote and maintain the normal metabolism of cells.
Sources and functions of peptides
The functional peptides can be divided into plant protein peptide, animal protein peptide and microbial protein peptide according to the sample.
According to the specific types of raw materials, the common plant protein peptides include soybean peptide, corn peptide, wheat peptide, buckwheat peptide, chickpea peptide, etc. The most studied animal protein peptides are milk peptide, insect peptide, meat peptide, egg peptide, fish peptide and various marine biological peptides. The common microbial protein peptides are Spirulina peptide, yeast protein peptide and so on.
Research background of peptide
Since British physiologists Bayliss and Starling discovered trypsin (peptide) in animal gastrointestinal tract in 1902, peptide research began to bring surprise to human again and again.
In 1958, American biochemist Dr. Herber Boyer successfully developed the active peptide by using cell recombination technology. It controls the quantity, quality and speed of protein synthesis, and controls human disease and aging. In that year, he won the Nobel Prize in biology.
In 1990, Dr. Rudman first used active peptides to explain the causes of human diseases and aging, and applied them to the field of anti-aging and disease prevention.
In 1993, Science reported that Herber Boyer and Dr. Rudman's application results of active peptides were evaluated by authoritative institutions, and the value was more than 300 billion US dollars.
Until 2015, the discovery and research results of peptides won 9 Nobel prizes, and peptide health research is in the ascendant.
