%0 Journal Article %T Enzymatic and Non-Enzymatic Antioxidants in Plants %A O£¿uz Ayhan K£¿RE£¿C£¿ %J - %D 2018 %X Living things have defense mechanisms against environmental stresses. These mechanisms protect the organism against adverse effects of stress conditions. Stress responses are a complex process. Live systems can survive according to the compatibility of their responses to stress types. Antioxidant defense is the most important mechanism to combat stress in biological systems. As in animals, there is antioxidant defense in plants. It is difficult to clarify biological stress responses such as plants. Plants can fight against the negative effects of environmental stress through their antioxidant systems. The antioxidant system consists of enzymatic antioxidants such as Superoxide dismutase, Catalase, Ascorbate peroxidase, Glutathione peroxidase, Glutathione reductase, Dehydroaskorbate reductase, Monodehydroaskorbate reductase and Guaiacol peroxidase, as well as non-enzymatic antioxidants such as Ascorbic acid, Glutathione, ¦Á-Tocopherol, Carotenoid and Phenolic compounds. This review, plants' enzymatic and non-enzymatic antioxidants were explained and it was intended to provide contribution to literature %K Antioksidan sistem %K Bitki %K Enzimatik antioksidan %K Enzimatik olmayan antioksidan %K Stres %U http://dergipark.org.tr/bitlisfen/issue/41777/463251
