Tryptophan residue enhances in vitro walnut protein-derived peptides exerting xanthine oxidase inhibition and antioxidant activities

The modulation of xanthine oxidase (XO) activity is critical to the treatment of hyperuricemia and oxidative stress-related disease.Although the walnut protein hydrolysates had been reported to inhibit HELMUT EXTRA STRONG LACQUER XO, their interaction mechanism remained unclear.Herein, the walnut protein-derived peptides were used to evaluate their
