Impact of phosphatidylethanolamine on the antioxidant activity of α-tocopherol and trolox in bulk oil.

Journal of Agricultural and Food Chemistry, 2015
The amphiphilic phospholipids dioleoylphosphatidylcholine (DOPC) and dioleoylphosphatidylethanolamine (DOPE), can form reverse micelles in bulk oils, which affects lipid oxidation chemistry.

ALPHA-TOCOPHEROL AND ALPHA-TOCOPHEROL PHOSPHATE IN THE PROPHYLAXIS OF THROMBOEMBOLISM

Archives of Surgery, 1953
IN THE first seven months of 1949, thromboembolic disease developed postoperatively in nine patients in the surgical service of the Snyder-Jones Clinic, Winfield, Kan., and two of these nine patients died with pulmonary embolism. During the summer of 1949, we learned of the work later reported by Ochsner, DeBakey, and DeCamp, and by Kay and his co ...

Tocopherols in foods and fats

Lipids, 1971
AbstractMethods are now available for the determination of all the specific tocopherol forms found in nature. Although the greatest interest centers on alpha‐tocopherol, much information has been gathered on the amounts of individual tocopherols in foods and fats contributing to the human diet.

Chromatographic separation of tocopherols

Journal of Chromatography A, 2001
alpha-, beta-, gamma-, and delta-Tocopherols were separated by reversed-phase high-performance thin-layer chromatography (C18RP-HPTLC), normal-phase high-performance liquid chromatography (NP-HPLC), reversed-phase high-performance liquid chromatography (C18RP-HPLC), and gas chromatography (GC). The selected topological indices based on connectivity (M,

Tocopherols in nuts

Journal of the Science of Food and Agriculture, 1962
AbstractThe α‐ and γ‐tocopherol contents of eight different nuts have been determined spectrophotometrically on chromatographic fractions. Thin layer chromatography was applied to study the tocopherol pattern.The tocopherol contents were generally fairly high, but the values for α‐tocopherol varied greatly.

Enzymatic Sulfation of Tocopherols and Tocopherol Metabolites by Human Cytosolic Sulfotransferases [PDF]

Bioscience, Biotechnology, and Biochemistry, 2011
Tocopherols are essential micronutrients for mammals widely known as potent lipid-soluble antioxidants that are present in cell membranes. Recent studies have demonstrated that most of the carboxychromanol (CEHC), a tocopherol metabolite, in the plasma exists primarily in sulfate- and glucuronide-conjugated forms.

Binding of ascorbic acid and α-tocopherol to bovine serum albumin: a comparative study.

Molecular Biosystems, 2014
Binding of ascorbic acid (water-soluble antioxidant) and α-tocopherol (lipid-soluble antioxidant) to bovine serum albumin (BSA) has been studied using isothermal titration calorimetry (ITC), in combination with fluorescence spectroscopy, UV-vis ...

Tocopherol Therapy in Acanthocytosis

Pediatrics, 1971
Acanthocytosis or a-beta-lipoproteinemia is a rare inborn error of metabolism known also as the "Bassen Kornzweig syndrome."1 We had See Images in the PDF File the opportunity to examine a Jewish girl, H.F., 11 years old, with a-beta-lipoproteinemia. The girl has healthy parents of Turkish origin who are first cousins, and
