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 ...

Chemical Composition and Antioxidant Activity of Lipids from Ficus Carica l. Fruits

open access: yesChemistry Journal of Moldova: General, Industrial and Ecological Chemistry, 2023
Samples of oils from seven types of Ficus carica L. fruits from Algeria were investigated through determinations of their chemical characteristics, quantifying sterols and tocopherols, and analysis of the fatty acids profiles using gas chromatography ...

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

Absence of VLDL secretion does not affect α-tocopherol content in peripheral tissues

open access: yesJournal of Lipid Research, 2006
α-Tocopherol is a lipid-soluble antioxidant that helps to prevent oxidative damage to cellular lipids. α-Tocopherol is absorbed by the intestine and is taken up and retained by the liver; it is widely presumed that α-tocopherol is then delivered to ...

Regional Characterization Study of Fatty Acids and Tocopherol in Organic Milk as a Tool for Potential Geographical Identification

open access: yesFoods, 2020
Reliable geographical identification can protect producers of excellent agroproducts, and also provide reliable purchasing information to satisfy consumers. Therefore, this study aimed to evaluate the regional and monthly variation in fatty acid (FA) and

Studies on the distribution of tocopherol in human serum lipoproteins*

open access: yesJournal of Lipid Research, 1960
The tocopherol content of human serum proteins, isolated by density gradient and homogeneous density procedures, was determined by the Emmerie-Engel and phosphomolybdic acid methods. Serum tocopherol is found primarily in the lipoproteins.

Effects of glutathione on the alpha-tocopherol-dependent inhibition of nuclear lipid peroxidation.

open access: yesJournal of Lipid Research, 1989
Endogenous alpha-tocopherol levels in isolated rat liver nuclei were determined to be 0.045 mol% (mol alpha-tocopherol per mol phospholipid x 100).

Tocopherols in Micro-organisms [PDF]

open access: yesNature, 1959
ALTHOUGH the tocopherols, and in particular α-tocopherol, are widely distributed in Nature, they have not so far been identified in micro-organisms. The only micro-organism that has been adequately studied is bakers' yeast, which has been found to contain no tocopherol, although it contains another substance with vitamin E-like activity1.

Scientific Opinion on Dietary Reference Values for vitamin E as α‐tocopherol

open access: yesEFSA Journal, 2015
Following a request from the European Commission, the EFSA Panel on Dietetic Products, Nutrition and Allergies (NDA) derived Dietary Reference Values (DRVs) for vitamin E. In this Opinion, the Panel considers vitamin E as α‐tocopherol only.
