The observed antioxidative activity derived from the identified peptide was confirmed by chemically synthesizing a peptide with the sequence Ser-Asn-LeuCys-Arg-Pro-Cys-Gly and then characterizing its
antioxidative properties. The peptide was found to scavenge radicals of DPPH and ABTS with IC50
values of *0.39 and *0.35 mg/ml, respectively(Fig. 3a), which were almost equivalent to those of
antioxidative peptides identified from enzymatic hydrolysate of crocein croaker (Pseudosciaena crocea) (Wang et al. 2013).The reducing power and antioxidative activity of this peptide were also evaluated. The peptide’s antioxidative activity, as determined by FRAP assay, was linear in relation to peptide concentration
