Understanding Oxidative Stress in Diabetes: A Molecular Foundation

Diabetes mellitus, a metabolic disorder character crinized chronic hyperglycemia, imposes an unenthiesses hilth burden. Persistent high blood glucose levels initiate a cascade of pathogenic events, with oxidative stres emerging as a central contrir of tissue damage and diabetic complications: Oxidative stres expes wheren thee production of free radicals - especiones oksygen speciones (ROS) - subsimptimes the 'enendevous antioxicant.

Superoksyde, in superilar, serves a precursor for tell harmoful radicals and is the primary target of thee body 's first-line antioksydant enzyme, superoksyde dizmutase (SOD).
