Alpha-tocopherol and gamma-tocopherol concentration in vegetable oils [PDF]
Vegetable oils are the richest dietary sources of vitamin E. Vitamin E determination levels in foods are of great importance to adjust the ingestion of nutrients by the population.

Tocopherol in human platelets.
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

Tocopherols in Micro-organisms [PDF]
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.

Ubiquinone and Tocopherol in Birds [PDF]
UNLIKE the rat and the rabbit, it seems from nutritional studies made by several groups of workers that the chicken needs little vitamin E, providing its diet contains an adequate supply of selenium and only limited amounts of unsaturated fat1–3. Since tissue-levels of ubiquinone in the rat4 and rabbit5 are high compared with those given for some other

Tocopherol vs. Tocopherol Acetate as a "Sparer" of Vitamin A.
Summary1. In bio-assays of vitamin A, α-tocopherol, but not α-tocopherol acetate, increased the rate of gain in the assay period. In a post-assay depletion period, animals that received α-tocopherol during the assay period survived 30-80% longer than controls.2.

Tocopherols in cancer: An update [PDF]
Tocopherols exist in four forms designated as α, β, δ, and γ. Due to their strong antioxidant properties, tocopherols have been suggested to reduce the risk of cancer. Cancer prevention studies with tocopherols have mostly utilized α‐tocopherol. Large‐scale clinical trials with α‐tocopherol provided inconsistent results regarding the cancer‐preventive ...

Genetic parameter estimates for plasma oxidative status traits in slaughter pigs [PDF]
The aim of the present study was to assess the effect of sex and to estimate genetic parameters for several traits related to plasma oxidative status in slaughter pigs, i.e., ferric reducing ability of plasma (FRAP), concentrations of a-tocopherol and ...

BACKGROUND There is evidence that medications or vitamins that increase the levels of brain catecholamines and protect against oxidative damage may reduce the neuronal damage and slow the progression of Alzheimer's disease.

Tocopherol and plastoquinone synthesis in spinach chloroplasts subfractions [PDF]
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.

Influence of soy protein’s structural modifications on their microencapsulation properties: a-tocopherol microparticles preparation [PDF]
Enzymatic and chemical modifications of soy protein isolate (SPI) were studied in order to improve SPI properties for their use as wall material for a-tocopherol microencapsulation by spray-drying.
