Tocopherol and plastoquinone synthesis in spinach chloroplasts subfractions [PDF]
, 1980 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.

Tocopherol in human platelets.
Journal of Lipid Research, 1975 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

Generation of superoxide and singlet oxygen from α-tocopherolquinone and analogues. [PDF]
, 2007 Three potential routes to generation of reactive oxygen species from a tocopherolquinone have been identified. The quinone of the water-soluble vitamin E analogue Trolox C (Trol-Q) is reduced by hydrated electron and isopropanol a hydroxyalkyl radical ...

Absence of VLDL secretion does not affect α-tocopherol content in peripheral tissues
Journal of Lipid Research, 2006 α-Tocopherol is a lipid-soluble antioxidant that helps to prevent oxidative damage to cellular lipids. α-Tocopherol is absorbed by the intestine and is taken up and retained by the liver; it is widely presumed that α-tocopherol is then delivered to ...
