The research team led by Lai Ren, researcher of Kunming Institute of zoology, Chinese Academy of Sciences and Lin Donghai, researcher of Shanghai Institute of medicine, Chinese Academy of Sciences has made new progress in the research of peptide antioxidant system In 2009, the research team proposed the peptide antioxidant system encoded by the gene and named it "the third set" (Mol Cell proteomics, 2009,8:571-583) Based on the work of the "third set" antioxidant system, the research team conducted in-depth research on the scavenging efficiency, speed and mechanism of free radicals from the peptide antioxidant system The results showed that the antioxidant peptide could scavenge more than 80% of artificial free radicals (less than two seconds) very quickly, and its speed is the current commercial antioxidant (such as 2,6-di-tert-butyl-4-methyl Phenol and vitamin E) The mechanism of antioxidation showed that the reduced cysteine in the antioxidant peptide sequence played a key role in the rapid scavenging of free radicals.
