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

Animal 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

Agricultura, 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.

The uptake of tocopherols by RAW 264.7 macrophages

Nutrition Journal, 2002
Background Alpha-Tocopherol and gamma-tocopherol are the two major forms of vitamin E in human plasma and the primary lipid soluble antioxidants. The dietary intake of gamma-tocopherol is generally higher than that of alpha-tocopherol.

Prevalence of vitamin E inadequacy, dietary intake and sources of alpha-tocopherol, and predictors of alpha- and gamma-tocopherol status in adolescent girls in Central Mozambique

Journal of Nutritional Science, 2023
An adequate alpha-tocopherol status is important for females at reproductive age. We studied the dietary intake and sources of alpha-tocopherol and alpha- and gamma-tocopherol status indicators in 14–19-year-old girls in Central Mozambique.

Tocopherol and plastoquinone synthesis in spinach chloroplasts subfractions [PDF]

, 1980
Subfractions isolated from intact purified spinach chloroplasts are able to prenylate the aromatic moiety of -tocopherol and plastoquinone-9 precursors. The biosynthesis of -tocopherol and plastoquinone-9 is a compartmentalized process.
