Mechanism of tocopherol transfer by human α-tocopherol transfer protein (α-hTTP)
… to describe a family of eight stereoisomers of tocopherols. Selective retention of a-tocopherol in the human circulation system is regulated by the a -Tocopherol Transfer Protein (a-TIP). Using a fluorescently labelled a-tocopherol (NBD-a-Toc) synthesized in our laboratory, a fluorescence …

Synthesis of fluorescent analogues of a-tocopherol as ligands for the human a-tocopherol transfer protein (a-TTP) /
… in vivo localization and trafficking of a-tocopherol (a-Toe), the most biologically active form of vitamin E, between lipid environments, tocopherols are required that can be followed by teclu1iques such as confocal microscopy and fluorescence resonance energy transfer (FRET) assays. To …

Investigation of the mechanism of transfer of a-tocopherol by the human a-tocopherol transfer protein (H-a-TTP) /
The human a-tocopherol transfer protein (h-a-TTP) is understood to be the entity responsible for the specific retention of a-tocopherol (a-toc) in human tissues over all other forms of vitamin E obtained from the diet. a-Tocopherol is the most biologically active form of vitamin E, and to date has …

Lutein and α-tocopherol biodistribution in animal models
Carotenoids and vitamin E (α-Tocopherol; αT), the two most plentiful groups of lipophilic antioxidants in plants, serve important functions in the human body. The carotenoid lutein is prevalent in green leafy vegetables and is one of the most abundant carotenoids in serum and tissues. Of particular …

Probes of tocopherol biochemistry: fluorophores, imaging agents, and fake antioxidants
… result of a selection process mediated by the α-tocopherol transfer protein (α-TTP), α-tocopherol is the only form of vitamin E retained in the body. This chaperon protein has been well studied because of its role in vitamin E transport. Furthermore, malfunctions of α-TTP cause vitamin E …

Genetic Variation Among Maize Genotypes for Carotenoid and Tocopherol Compounds
We analyzed the amount of carotenoid and tocopherol fractions at early, intermediate, and late stages of kernel development; and the rate of deposition during this period. Although there were differences among genotypes, general tendency was that both classes of compounds accumulated rapidly in …

Natural versus synthetic alpha-tocopherol using cell and animal models
Vitamin E (α-tocopherol, α-T) is one of nature’s famous lipid-soluble chain-breaking antioxidants. Although originally discovered in the 1920s as an essential rodent fertility factor, decades of research also demonstrate α-T’s essentiality in the lipid-rich, oxidative-stress-prone environment of …

Ascorbic Acid and Tocopherol Concentration of Hydroponic and Soil-Grown Lettuces
… lettuce contains as much ascorbic acid and tocopherol as soil-grown lettuce. We analyzed four varieties of lettuce, including: Waldmann's Dark Green, Red Lollo Antago, Red Romaine Annapolis, and Butterleaf. The first three were obtained from the Mountain View Montessori of Reno's greenhouse. …

Tocopherol content of soybean lines with mid-oleate and 1%-linolenate
… Merr.] oil is an important commercial source of tocopherol (Vitamin E). Some genetic modifications of the fatty ester composition of soybean oil have resulted in changes in the content of total tocopherol and its components. The objective of this study was to compare the tocopherol content of 20 …

The Synthesis of α-Tocopentaenol (αT5), a Fluorescent Analogue of α-Tocopherol
This thesis is focused on the investigation of synthesizing a fluorescent analogue of vitamin E, α-tocopentaenol (αT5). α-Tocopentaenol contains five conjugated double bonds across the phytyl tail, resulting in its fluorescence characteristics. Different methodologies of preparation were attempted …

Tocopherol (vitamin E) content in invasive browse species on underutilized Appalachian farmland
The tocopherol (Vitamin E) content of forage from three invasive shrub species was measured to assess the value of the shrubs as a source of vitamin E for goats browsing on overgrown Appalachian pastures. Plant leaf clusters were collected from multiflora rose (Rosa multiflora Thunb.), autumn olive …
