Tocochromanols – bioactive compounds of oilseeds. From biosynthesis to biomarkers
Journal Title: Rośliny Oleiste - Oilseed Crops - Year 2011, Vol 32, Issue 1
Abstract
Tocochromanols belong to a group of lipid-soluble antioxidants present in plastids. Oilseeds are particularly rich in tocochromanols with their average concentration ten-fold higher than in other plants. In addition to their numerous functional roles in photosynthetic organisms, these compounds are also essential components of animal and human diet. This paper describes the process of biosynthesis of tocopherols, tocotrienols and plastochromanol-8 through the examination of anatomical parts of the plant taking the rapeseed (Brassica napus L.) as an example. In a systematic way, it also describes the characteristics of this group of compounds acting in the human body, ranging from antioxidant properties to the physiological changes generating a series of biomarkers depicting the course of certain biological processes.
