CELL INJURY-2 In previous discussion we have discussed Definition and explanation of cell injlury Mechanism of injury Initiate Step- Membrane Injury Normal cell VS Damaged cell Mitochondrial Dysfunction in Cell Injury So now we will continue our discussion with Over Oxygen Free Radical Production: MECHANISMS OF FREE RADICAL-INDUCED CELL INJURY Free radical over producing is a key event in the procedure of cell injury. Free radicals are chemical species with a single unpaired electron in an outer orbital. It is extremely unstable and prone to react with inorganic or organic chemicals. It binds to large molecules such as nucleic acids and proteins, change the later’s normal structure, initiate the autocatalytic reactions. Broken large molecules to produce more free radicals, the cascade goes on. https://www.hanxinclinic.com/index.php/2019/12/07/cell-injury-2-2/
