Description
Technical field
The present invention relates to albumen fields, more particularly, to a kind of biologically active polypeptide GIQDPKEP and preparation method thereof and answer
With.
Background technology
During cow's milk is through lactobacillus-fermented, a part of protein in cow's milk is metabolized by lactic acid bacteria to be utilized, concurrently
A series of biochemical reactions have been given birth to, so that protein is become polypeptide or free amino acid, is digested or passes through
The absorption and transport of intestinal epithelial cell is directly entered the blood circulation of human body.There is also the eggs of some itself synthesis for lactic acid bacteria thalline
White matter polypeptide fragment is utilized for bacterial growth.In these polypeptides, some is referred to as " raw with special physiological function
Object active peptide ".
It is particularly important that safe biologically active peptide is found in natural food source.In recent years, it has been found that some foods
The polypeptides matter in object source has good bioactivity, such as corn small peptide, soybean peptide, cow's milk polypeptide.These polypeptides can
To be obtained by number of ways such as microbial fermentation, digestion enzymolysis, and biologically active polypeptide is by 2~20 mostly
Amino acid residue forms, and molecular weight is less than 6000Da, contains a certain amount of hydrophobic amino acid, aromatic amino acid.
Immune-active peptides are to obtain and prove that one kind biology of its physiological activity is living from breast for the first time after opioid peptides discovery
Property polypeptide.Jolles in 1981 et al. has found for the first time, using trypsin hydrolysis people lactoprotein, can obtain an amino acid sequence
It is classified as the hexapeptide of Val-Glu-Pro-Ile-Pro-Tyr, experiment in vitro proves that the peptide can enhance Turnover of Mouse Peritoneal Macrophages pair
The phagocytosis of sheep red blood cell (SRBC).Migliore-Samour et al. has found the hexapeptide Thr-Thr-Met-Pro- from casein
Leu-Trp can stimulate sheep erythrocyte to the phagocytosis of mouse peritoneal macrophages and enhancing for kerekou pneumonia primary
The resistance of bacterium has anti-inflammatory properties.Newborn source peptide (PGPIPN) the feeding rat of Li Su duckweeds et al. synthesis finds that rat abdominal cavity is huge
The phagocytosis of phagocyte and the relevant anti-inflammatory properties of red blood cell have significant enhancing.
Studies have shown that immune-active peptides can not only enhance immunity of organisms, the proliferation of body lymphocyte, enhancing are stimulated
The phagocytic function of macrophage promotes the release of cell factor, the increase for promoting the macrophage nitric oxide amount of inducing, raising machine
Body resists the ability of extraneous pathogenic infection, reduces body incidence, and will not cause the immunological rejection of body.
Aging is a natural phenomena, and process is often accompanied by the variation of antioxidant levels, organ-tissue, immune factor,
Complicated variation occurs for middle cell factor, such as the trend that proinflammatory cytokine IL-6, IL-4, TNF-α presentation increase, IL-6
It is all considered to play an important role in the generating process of geriatric disease with TNF-a.With science of heredity and molecular biology
Development, the research of biological decay mechanism achieve gratifying progress.Researcher by using some model organisms, as mouse,
The term single gene mutating experiment of drosophila and caenorhabditis elegan etc. finds that some genes can dramatically increase service life of these organisms and reach
As many as 6 times.
Anti-aging peptide as a kind of emerging antidotal agent, in terms of physiological function have amino acid cannot compare it is excellent
Gesture can generate promotion or inhibiting effect to the enzyme in organism, improve the absorption to minerals and other nutrients and profit
With removing interior free yl enhances the resistance to oxidation of body itself, to slow down aging.Therefore, the nutrition and health care of biologically active peptide
Effect has become the emphasis of domestic and foreign scholars' subject study.Qiu Juan et al. pass through experimental studies have found that, milk-derived bioactive micro peptide
Life span of drosophila melanogaster can effectively be extended, delay its aging, and also there is preferable antioxidation, thus it is speculated that may be wherein to be rich in coloured glaze
Base peptides.SOD vigor in serum, reduces its lipid in discovery bovine colostrum extract energy conspicuousness raising the elderly's body such as the brightness in week
Peroxide and enhancing body resistance to oxidation, have certain anti-senescence function.
