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

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.

α-Tocopherol in plasma and milk from organically managed dairy cows fed natural or synthetic vitamin E or seaweed [PDF]

open access: yes, 2012
The objective was to compare the effects of supplementing lactating dairy cows with synthetic (All-rac), natural (RRR) α-tocopheryl acetate or seaweed with a control on the concentration of α-tocopherol in blood and milk.

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.

Impaired discrimination between stereoisomers of alpha-tocopherol in patients with familial isolated vitamin E deficiency.

open access: yesJournal of Lipid Research, 1993
We assessed whether patients with familial isolated vitamin E deficiency could discriminate between natural (RRR-) and synthetic (SRR-) stereoisomers of alpha-tocopherol labeled with six (d6) or three (d3) deuterium atoms, respectively.

Identification of SNP and InDel variations in the promoter and 5′ untranslated regions of γ-tocopherol methyl transferase (ZmVTE4) affecting higher accumulation of α-tocopherol in maize kernel

open access: yesCrop Journal, 2019
Deficiency of vitamin-E or tocopherol causes neurological and cardiovascular disorders in humans. Though maize kernel is rich in total tocopherol, the level of α-tocopherol possessing the highest vitamin-E activity is low.

Regulation of Tocopherol Biosynthesis During Fruit Maturation of Different Citrus Species

open access: yesFrontiers in Plant Science, 2021
Tocopherols are plant-derived isoprenoids with vitamin E activity, which are involved in diverse physiological processes in plants. Although their biosynthesis has been extensively investigated in model plants, their synthesis in important fruit crops as
