The invention relates to the technical field of polypeptides and discloses synthetic polypeptide as well as a synthesis method and application thereof. An amino acid sequence of the synthetic polypeptide disclosed by the invention is shown as SEQ ID NO: 1; the synthetic polypeptide is a polypeptide which is obtained by substituting, deleting or adding one or more than two amino acids on the sequence shown as SEQ ID NO: 1 and has osteoblast proliferation activity. The invention provides novel active pentapeptide; the novel active pentapeptide has the effect of remarkably promoting proliferationof mouse embryo osteoblast precursor cells and has a foundation of preventing osteoporosis diseases; the novel active pentapeptide can be widely applied to the fields including foods, health-care products, medicines and the like.

Synthetic polypeptide as well as synthesis method and application thereof

The invention belongs to the field of bio-pharmaceuticals, in particular to a polypeptide and a preparation method and application thereof. The amino acid sequence of the polypeptide is shown as SEQ ID NO:1. The polypeptide uses a polypeptide synthesizer and is synthesized through a solid-phase synthesis method. An experiment result indicates that the polypeptide has a good function of resisting oxidation and inhibiting beta-amyloid protein aggregation, meanwhile, the polypeptide is applied to H2O2 to induce and generate the nerve cell of superoxide to generate an oxidation resistance function, the polypeptide has a good effect, can be used for preparing a medicine for resisting oxidation and inhibiting beta-amyloid protein aggregation, and a medicine for treating nervous system diseases,and the polypeptide has the advantages of wide application range and good economic and social effect.
