The invention relates to the field of
protein, in particular to bioactive peptides VPYPQRDMPI and a preparation method and application thereof. An
amino acid sequence of the bioactive peptides VPYPQRDMPI is Val-Pro-Tyr-Pro-Gln-Arg-Asp-Met-Pro-Ile. By means of the in-vitro anti-
inflammation activity experiment and in-vivo anti-
ageing experiment, it is verified that the peptides VPYPQRDMPI has the good anti-
inflammation activity and anti-
ageing activity, on one hand, the bioactive peptides VPYPQRDMPI can promote macrophage to secrete
cell factors, increasing of the induced volume of macrophage
nitric oxide is promoted, the external
pathogen infection resisting capacity of
organism is improved, and the incidence of the
organism is lowered; on the other hand, the
vitality of in-vivo peroxidasesystem resistance can be increased, the exogenous stimulus resisting function of the
organism is enhanced, and then the probability of organism
ageing, senility and sickness is lowered, and great significance on developing foods, health-care products and
medicine which have the anti-
inflammation and anti-ageing functions is achieved.
