CAD and hepatocellular carcinoma: In this study, based on the above results of antioxidant activities of MPs and CPs, MPs hydrolyzed by alcalase (MPs-A) and CPs hydrolyzed by dispase (CPs-D) were chosen to evaluate their cytoprotective effects against oxidative damage in human hepatocellular carcinomas (HepG2) cells caused by H2O2.
