Abstract

The invention relates to the field of protein, and in particular to a bioactive polypeptide SKHSSLDCVL, and a preparation method and application thereof. An amino acid sequence of the bioactive polypeptide SKHSSLDCVL is Ser-Lys-His-Ser-Ser-Leu-Asp-Cys-Val-Leu. An in-vitro antioxidant experiment and an in-vitro immunological function promoting experiment verify that the bioactive polypeptide SKHSSLDCVL has better antioxidant biological activity and a better immune modulating function; on one hand, the bioactive polypeptide SKHSSLDCVL has better antioxidant activity and is capable of removing free radicals in a body and increasing the quality of life; on the other hand, the bioactive polypeptide SKHSSLDCVL is capable of enhancing in-vitro proliferation ability of lymphocytes and macrophages, promoting the ability of swallowing neutral red by the macrophages, increasing the ability of defending external pathogen infection by the body and reducing the morbidity of the body, and has a very important significance in developing food, healthcare products and drugs having an immune modulating function and an antioxidant function.

Description

technical field

[0001] The invention relates to the field of proteins, in particular to a biologically active polypeptide SKHSLDCVL and its preparation method and application. Background technique

[0002] During the fermentation process of milk by lactic acid bacteria, a part of protein in milk is metabolized and utilized by lactic acid bacteria, and a series of physiological and biochemical reactions occur, making the protein into polypeptides or free amino acids, which are digested and absorbed by the human body or absorbed and transported by small intestinal epithelial cells directly into the blood circulation of the human body. Among these peptides, some have special physiological functions and are called "bioactive peptides".

[0003] Oxidation reaction and oxidative metabolism are crucial for food and human body, and free radicals and reactive oxygen species cause a series of oxidation reactions. When excessive free radicals are formed, they will exceed the protecti...
