How can you use “tocopherol” in a sentence? Here are some example sentences to help you improve your vocabulary:
To define the time course of tocopherol (or tocopheryl quinone) accumulation, adherent cells (2 × 10 6/well) were subcultured in 12 well falcon tissue culture plates with medium enriched with about 5 μM tocopherol (or about 0.5 μM quinone) (3 ml/well).
A 50 μl aliquot of tocopherol (or tocopheryl quinone) solution in ethanol was placed in glass tube and dried under N 2 . After the addition of 1.0 ml of 7.5% BSA the mixture was vortexed for 2 min, 74.
It has been proposed that vitamin E may incorporate into cellular membranes by association of the tocopherol side chain with the polyenoic fatty acid residues in the membrane fatty acids [ 15 19 ] . This interaction may stabilize cell membranes by making highly unsaturated fatty acids less liable to peroxidation as well as by making highly unsaturated fatty acids less available for phospholipid hydrolysis by phospholipase [ 15 16 ] . The latter action may reduce mobilization of arachidonic acid (AA) from the membranes and in this way reduce the amount of AA available as a substrate to cyclooxygenase and/or lipoxygenase to produce eicosanoids with mitogenic and with inflammatory properties [ 17 20 ] . Other possible antitumor actions include: induction of apoptosis, interference with hormone production, modulation of cellular signaling and gene transcription, and induction of differentiation [ 4 21 22 23 24 ] .
The tocopherol (or tocopheryl quinone) was measured using a HPLC equipped with a Coulochem II Electrochemical Detector, a ESA Model 580 Solvent Delivery Module, a Column Catecholamine HR-80 (C18, 3 mm, 8 cm), a Model 5011 Analytical Cell, a Model 5020 Guard Cell (Chelmsford, MA), a PE Nelson 900 Series Interface with PE Nelson Turbochrom V4 software (Perkin Elmer, San Jose, CA).
During the course of the cell culture experiment, a 400 μl aliquot of medium was removed every 2 hr and placed in a glass vial for tocopherol (or quinone) measurement and the remaining medium removed.
