Formation of RRR-α-tocopherol in rumen and intestinal digestibility of tocopherols in dairy cows

open access: yesAnimal Nutrition, 2023
Tocopherol sources in diets are often a combination of all-rac-α-tocopheryl acetate (synthetic α-tocopherol) from vitamin supplements and natural tocopherols and 2R-(4′R, 8′R)-5,7,8-trimethyltocotrienol (α-tocotrienols) from the feed sources. Synthetic α-

DETERMINATION OF VITAMIN E CONTENT IN SUNFLOWER OILS AVAILABLE ON THE ROMANIAN MARKET

open access: yesAgricultura, 2021
Vitamin E is soluble in fat and alcohol, withstands temperatures up to 250ºC, but is sensitive to light and oxygen. Very high or very low temperature values reduce the amount of tocopherol in food by up to two-thirds.

Engineering tocopherol biosynthetic pathway in lettuce

open access: yesBiologia Plantarum, 2011
In order to increase tocopherol content, genes encoding Arabidopsis homogentisate phytyltransferase (HPT) and γ-tocopherol methyltransferase (γ-TMT) were constitutively over-expressed in lettuce (Lactuca sativa L. var. logifolia), alone or in combination.
