1. Alpha-Tocopherol is an important lipid-soluble antioxidant. 2. Like cholesterol, carotenoids and tocopherols are transported by lipoproteins. 3. Tocopherols represent an alternate sedimentary source of pristane in sediments and petroleum.4. Kay's study used only alpha-tocopherol . 5. Annatto tocotrienol has the highest tocotrienol concentrations, and is tocopherol -free. 6. It is the ester of acetic acid and tocopherol ( vitamin E ). 7. Alpha-tocopherol does not address this mutation-causing compound, he said. 8. The proportion of vitamin E to other tocopherols in a nutrient source varies greatly. 9. This form, known as 2-ambo tocopherol , is no longer made .) 10. :* Mention modern research into plant metabolic engineering to increase tocopherols and other antioxidants?
