Choline and methionine supplementation in layer hens fed flaxseed: effects on hen production performance, egg fatty acid composition, tocopherol content, and oxidative stability

open access: yesPoultry Science, 2021
: Choline is an essential nutrient in laying hen diets and is needed for the formation of phosphatidylcholine (PC), that serves as a rich source of long chain (≥20 C) n-3 fatty acids (FA) in eggs.

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.

Tocopherols in Sunflower Seedlings under Light and Dark Conditions

open access: yesThe Scientific World Journal, 2015
The objective of this study was to evaluate the dynamics of tocopherols in cotyledons and radicles from sunflower seeds with high and low total tocopherol content, mainly in the α-tocopherol form, and from seeds with increased proportions of β-, γ-, and ...

Tocopherol in human platelets.

open access: yesJournal of Lipid Research, 1975
A spectrophotometric method was used to determine the total tocopherol levels in platelets, plasma, and erythrocytes from human subjects. The platelets contained about three times as much total tocopherol per cell as erythrocytes. This difference was not

Generation of superoxide and singlet oxygen from α-tocopherolquinone and analogues. [PDF]

open access: yes, 2007
Three potential routes to generation of reactive oxygen species from a tocopherolquinone have been identified. The quinone of the water-soluble vitamin E analogue Trolox C (Trol-Q) is reduced by hydrated electron and isopropanol a hydroxyalkyl radical ...

Assessment of vitamin E status in patients with systemic inflammatory response syndrome: plasma, plasma corrected for lipids or red blood cell measurements? [PDF]

open access: yes, 2009
<b>Background:</b> There is some evidence that the plasma vitamin E status is perturbed as part of systemic inflammatory response and correcting this with other plasma markers may not lead to reliable results.
