Gıdalardaki Doğal Antioksidan Bileşikler

Vücut hücrelerinde reaktif oksijen türlerinin (ROS) oluşması veya artması çeşitli kanser türleri, kalp-damar hastalıkları, sinirsel hastalıklar (Alzheimer, Parkinson, Multiple sclerosis, Down sendromu vb.) katarakt ve tümör oluşumu gibi dejeneratif rahatsızlıklara direkt ya da indirekt olarak neden olabilmektedir. Doğal antioksidanlar, hücreleri ROS veya serbest radikallerin potansiyel zararlı etkilerinden koruyucu bir role sahiptir.  Antioksidan olarak bilinen diyet bileşenlerinin başlıca örnekleri karotenoidler, fenolik bileşikler, C vitamini ve E vitaminini içermektedir. Bu makalede, doğal antioksidan bileşikler ve etki mekanizmaları incelenmiştir.

Natural Antioxidant Compounds in Foods (Turkish with English Abstract)

 The liberation or generation of reactive oxygen species (ROS) within the body cells may directly or indirectly contribute to degenerative illnesses, such as the different types of cancer, cardiovascular and neurological diseases (e.g. Alzheimer, Parkinson, Multiple sclerosis, Down syndrome), cataracts and tumor formation. Natural antioxidants may have a role in protecting cells from the potentially deleterious effects of ROS or free radicals.  Notable examples of dietary compounds referred to as antioxidants include carotenoids, phenolics, vitamin C and vitamin E. In this article, natural antioxidant compounds and the mechanisms of their action are reviewed.
