Sekonder Metabolitler ve Rolleri

Öz

Sekonder metabolitler, bitkinin normal büyüme ve gelişmesi için ihtiyaç duymadığı ancak hücre metabolizmasının yan ürünü olarak bitkilerde üretilen kimyasal bileşiklerdir. Sekonder metabolitler, bitki yaşamı için elzem olmamakla birlikte bitki herhangi bir stres faktörü ile karşı karşıya kaldığında savunma mekanizması olarak sentezlenmeye başlarlar. Bazı sekonder metabolitler ilaçlar, tatlar, kokular, böcek öldürücüler ve boyalar gibi kimyasal olarak kullanılmaktadır ve bu nedenle büyük bir ekonomik değere sahiptir. Bu yeni teknolojiler, özellikle tıbbi bileşikler olmak üzere kimyasalların yenilenme kaynakları olarak yüksek bitkilerin sürekli kullanışlılığını genişletmeye ve geliştirmeye hizmet edecektir. Bu alandaki yoğunlaştırma çabalarının spesifik, değerli ve henüz bilinmeyen bitki kimyasallarının biyoteknolojik üretimine katkı sağlaması beklenmektedir.

Secondary Metabolites and Their Roles

Öz

Secondary metabolites are chemical compounds that the plant does not need for normal growth and development, but are produced in plants as by-products of cell metabolism. Although secondary metabolites are not essential for plant life, they start to be synthesized as a defense mechanism when the plant is exposed to any stress factor. A few secondary metabolites are used chemically, especially drugs, flavors, fragrances, insecticides and dyes, and therefore have a great economic value. These new technologies will serve to expand and improve the continuous usefulness of high plants as sources of chemicals regeneration, especially medical compounds. Concentration efforts in this area are expected to contribute to the biotechnological production of specific, valuable and unknown plant chemicals.
