Abstract

Reactive oxygen metabolites (ROMs) or free radicals are formed by mitochondria in all aerobic organisms as a product of normal metabolism in mitochondria and cause damage to macromolecules. Mitochondria are most vulnerable against these radicals in cells and ATP production decline as a result of mitochondrial dysfunction. It has recently been demonstrated that accumulation of oxidative damages with age has a significant role in apoptosis, some late-life diseases and aging process. Actually cells possess antioxidant defense mechanisms that detoxify free radicals. Because the defense mechanisms are inadequate during the aging process, oxidative damages are accumulated and cause diseases and aging. Anyway, sole cause of aging is not reduced to free oxygen radicals owing to the fact that aging is probably a multifactorial process

Özet

Reaktif oksijen metabolitleri ya da serbest oksijen radikalleri tüm aerobik organizmalar tarafından mitokondrilerin normal metabolizmasının bir ürünü olarak oluşur ve makromoleküllere zarar verir. Hücrelerde bu radikallere karşı en çok mitokondriler savunmasızdır ve mitokondrial disfonksiyon sonucu ATP üretimi baskılanır. Son zamanlarda yaşla birlikte oksidatif hasarın birikiminin; apoptosis, bazı ileri yaş hastalıkları ve yaşlanma sürecinde önemli bir rol oynadığı gösterilmiştir. Aslında hücreler serbest radikalleri detoksifiye eden antioksidan savunma sistemlerine sahiptir. Fakat antioksidan sistemler yaş la birlikte yetersiz kaldığı için oksidatif hasarlar birikerek, yaşlanmaya ve hastalıklara yol açar. Yine de yaşlılığın tek nedeni sadece serbest oksijen radikallerine bağlanamaz. Çünkü yaşlanma muhtemelen çok yönlü karmaşık bir süreçtir.
