Antioxidative peptide derived from yak blood and preparation and application of antioxidative peptide

Abstract

The invention provides a yak blood antioxidative peptide with intnstive antioxidation activity. The antioxidative peptide has a sequence of TLPDTEKQIKKQ, has reducing power up to 3.24 mg*mL<-1>, has a lipid peroxidation inhibition capability up to 2.43 mg*mL<-1>, an OH elimination capability up to 0.74 mg*mL<-1>, an ABTS<+> elimination capability up to 1.58 mg*mL<-1>, a DPPH elimination capability up to 1.59 mg*mL<-1>, a total antioxidation capability up to 4.27 mg*mL<-1>, has very good use prospects, and can be used for preparing corresponding antioxidants and applied to related antioxidation application fields.

Description

technical field [0001] The invention belongs to the technical field of antioxidant peptides, in particular to an antioxidant peptide derived from yak blood and its preparation and application. Background technique [0002] Yak is a special semi-primitive and semi-wild rare species scattered above 3,000 meters above sea level. Due to the special ecological environment and strong natural selection, yaks show excellent adaptability to low-oxygen environments, and can adapt to the environment that ordinary livestock cannot. Adapt to harsh ecological environments such as high altitude, low air pressure, and high hypoxia. China is the birthplace of yaks. There are a small amount of distribution in Mongolia, the former Soviet Union Central Asia, India, Bhutan, Sikkim, Afghanistan, Pakistan and other countries or regions adjacent to my country. Europe and the United States have also introduced yaks to raise, but the data is not available. its reporting. According to the data provid...
