Abstract

E vitamini tokoferoller olarak bilinen ve yüksek antioksidan özellikleri olan metabolitlerdir. Bitkiler tarafından üretilen E vitamininin kalp damar hastalıkları ve kanser gibi insan sağlığı açısından önemli hastalıklarda olumlu etkileri rapor edilmiştir. Tokoferollerin biyosentezinde bir grup metil transferaz ve siklaz enzimleri rol almaktadır. Tokoferollerin insan sağlığı üzerine birçok çalışma yapılmış olmasına rağmen, bu derleme tokoferollerin bitkilerdeki fonksiyonları üzerine odaklanmaktadır. Bu fonksiyonlar; antioksidan aktivite, Abiyotik stres koşullarına cevap, sinyal iletimi ve gen anlatımının düzenlenmesi gibi konuları içermektedir. Tokoferoller kuvvetli antioksidan özelliklere sahiptir ve bu özellikleri onların stres cevabı sinyal iletimi ve gen anlatımının düzenlenmesi gibi birçok etkisini açıklayabilmektedir. Bunun yanında tokoferollerin tüm etkilerini bu özellikleri ile açıklamak mümkün değildir. Bu sebeple bu derleme ile tokoferollerin biyosentezi, kimyasal yapısı, antioksidan aktiviteleri, abiyotik stres cevabı, sinyal iletimi ve gen anlatımının düzenlenmesi konularındaki literatürdeki güncel bilgiler tartışılmıştır.

Keywords: E vitamini, Tokoferol, Antioksidan aktivite, Abiyotik stres, sinyal iletimi, Gen anlatımı
