The pecking order of free radicals and antioxidants: lipid peroxidation, alpha-tocopherol, and ascorbate.

Archives of Biochemistry and Biophysics, 1993
Free radicals vary widely in their thermodynamic properties, ranging from very oxidizing to very reducing. These thermodynamic properties can be used to predict a pecking order, or hierarchy, for free radical reactions.

Red blood cell tocopherol and liver tocopherol in hyperlipemic rats as compared with plasma tocopherol

Lipids, 1985
AbstractIn rats with hyperlipemia induced by Triton WR‐1339, changes in tocopherol concentrations in plasma and RBC were compared with those in the liver and its subcellular fractions, microsomes and mitochondria.After daily injection with Triton, plssma total lipids at 3 days and 7 days, respectively, showed elevation 6.5 times and 15 times as high as

The Effect of α-Tocopherol on the Nitration of γ-Tocopherol by Peroxynitrite

Archives of Biochemistry and Biophysics, 1999
It has been proposed (S. Christen et al. Proc. Natl. Acad. Sci. USA 94, 3217-3222, 1997) that although alpha-tocopherol (alpha-TH) is an efficient antioxidant, the presence of gamma-tocopherol (gamma-TH) may be required to scavenge peroxynitrite-derived reactive nitrogen species.

η-Tocopherol (7-Methyltocol) : a New Tocopherol in Rice

Nature, 1956
RECENT publications have confirmed the existence of two previously unknown natural tocopherols in the lipid fractions of cereal grains (ɛ- and ζ-tocopherols) and have described methods for their separation by paper chromatography1–3. Thus six of the seven possible tocol structures produced by methylation of the tocopherol chroman nucleus have been ...

Tocopherols in Flaxseed

Journal of Agricultural and Food Chemistry, 1997
The tocopherol content of oil from eight flaxseed cultivars grown at four locations in western Canada for 3 years was determined to examine genotypic and environmental effects. Flaxseed contained an average of 9.3 mg/100 g of total tocopherol in the seed, with γ-tocopherol representing 96−98% of the total tocopherols.

Enhancement of flavonoid ability to cross the blood-brain barrier of rats by co-administration with α-tocopherol.

Food & Function, 2015
Vitamin E and polyphenols could exhibit a therapeutic role in the treatment of oxidative stress-induced neurodegenerative diseases. Therefore, their ability to cross the blood-brain barrier (BBB) represents an important issue to be explored by different ...
