Fig. 2From: Potent antioxidant peptides derived from honey major protein enhance tolerance of eukaryotic cells toward oxidative stressAntioxidant activities of THP and its hydrolysates. The superoxide-scavenging activity was assessed at 55 μg/mL of a intact THP or b its peptic hydrolysates at pH 2.0 (HP-p2) or c pH 4.0 (HP-p4) upon digestion with trypsin (+T), α-chymotrypsin (+α) or both (+T/α). Ctrl, reaction in the absence of protein. The corresponding DPPH reduction activities are shown on the top of each panelBack to article page
