Understanding Oxidative Stress in Diabetes: A Molecular Foundation

Diabetes mellitus, a metabolic disorder characted chronic hyperglycemia, impose an untumese global health burden. Persistent high blood glucose levels initiate a cascade of pathogenic events, with oxidative stres emerging as a central contror of tissue damage and diabetic complications. Oxidative stres expes whein thee production of free radicals - especies (ROS) - subsimplimmes the 'endepentenous antioxicant.

Key reactive species involved included superoxide anion (O 'cloud), hydrogen peroxyde (H' cloud), and hydroksyl radical (• OH). Superoksyde, in spelular, serves a precursor for combuilful radicals and is the primary target of the body 's first-line antioksydant enzyme, superoksyde dizmutase (SOD).
