Abstract: | Tocochroanols belong to a group of compounds comprising tocopherols and tocotrienols, known as vitamin E. Apart from the well known antioxidant properties of these compounds, there is increasing evidence accumulating for their additional function in men, manifesting in lowering of blood cholesterol level, anticancer and neuroprotective action, especially in the case of tocotrienols. The present article describes the structure of tocochromanols, their occurrence and biosynthesis in plants. The mechanism of antioxidant action of these compounds and recently recognized additional functions in plants and animals are presented. |
