How can you use “tocopherol” in a sentence? Here are some example sentences to help you improve your vocabulary:
It is a mixture of eight stereoisomers in equal amounts designated "dl" or all-rac tocopherol and does have antioxidant properties [ 4 ] . Thus, different forms of vitamin E can have different antioxidant properties as well as differences in their absorption, distribution, and metabolism [ 4 ] . There are also reports that some forms of vitamin E have activity against cancer cells in vitro [ 3 5 ] . For example, tocotrienol and vitamin E succinate are reported to have antiproliferative activity in human cancer cells whereas some forms of vitamin E are reported to induce apoptosis in cancer cell types but not in normal cell types [ 3 ] . Specifically, these apoptogenic forms include RRR-α-tocopheryl succinate and RRR-δ-tocopherol while the α, β, and γ tocopherol and acetate derivatives of tocopherol were not apoptogenic [ 3 ] . There are few reports on the use of vitamin E for treating tumorous cancers in vivo but the results are inconsistent [ 4 5 6 7 8 9 10 ] . It is therefore essential that the form of vitamin E used in any research study as well as the dosage and the mode of administration be defined.

These data show that the nmoles of tocopherol that accumulated in cells after 6 hr is very small compared to the amount in the medium.
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).
