“…To prevent oxidative stress, there is an ongoing balance between antioxidants and ROS. When there is an imbalance, ROS may accumulate and trigger oxidative injury by lipid peroxidation, and protein oxidation, accompanied by increased toxic product synthesis and cell death (Abadie, Malcom, Porter, & Svec, 2001;Choi, Park, & Park, 2002). Superoxide dismutases convert superoxide radicals to molecular oxygen and H 2 O 2 , and catalase decomposes H 2 O 2 to molecular oxygen and water (Tian, Cai, & Wei, 1998).…”
