CAT and Hyperglycemia: According to previously reported studies in diabetic model rats, a low level of antioxidants such as reduced glutathione (GSH), vitamin C, and vitamin E was found with low antioxidant enzyme activities, such as superoxide dismutase (SOD), glutathione‐S‐transferase (GST), glutathione peroxidase (GPx) catalase (CAT), and plasma insulin, while a high lipid peroxidation hyperglycemia was also seen (Zhang et al., 2020).
