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

Journal 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

Crop 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

Frontiers 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

Antioxidant Effect of Vitamins in Olive Oil Emulsion

Colloids and Interfaces, 2020
In this study, water-in-extra virgin olive oil emulsions were enriched with vitamins. Water-in oil emulsions are heterogeneous systems able to solubilize both hydrophilic and hydrophobic compounds.

Influence of Oxidants on the Stability of Tocopherol in Model Nanoemulsions: Role of Interfacial Membrane Organized by Nonionic Emulsifiers

Journal of Chemistry, 2018
Nanoemulsions were prepared by using emulsifiers with various sizes of hydrophilic and hydrophobic groups to determine the impact of interfacial characteristics on the stability of α-tocopherol incorporated into the nanoemulsions.

Modulation of Lipid Transport and Adipose Tissue Deposition by Small Lipophilic Compounds

Frontiers in Cell and Developmental Biology, 2020
Small lipophilic molecules present in foods of plant origin have relevant biological activities at rather low concentrations. Evidence suggests that phytosterols, carotenoids, terpenoids, and tocopherols can interact with different metabolic pathways ...

Vitamin E Bioavailability: Mechanisms of Intestinal Absorption in the Spotlight

Antioxidants, 2017
Vitamin E is an essential fat-soluble micronutrient whose effects on human health can be attributed to both antioxidant and non-antioxidant properties. A growing number of studies aim to promote vitamin E bioavailability in foods.
