The products of oxidation of the alpha-tocopherol model compound, 2,2,5,7,8-pentamethyl-6-chromanol (PH) by t-butyl hydroperoxide in chloroform varied with the amount of water present. In the presence of a trace of water, the main products were the spirodimer (PSD) and spirotrimer (PST...
d-alpha-Tocopherol, but not d-beta-tocopherol, negatively regulates proliferation of vascular smooth muscle cells at physiological concentrations. d-alpha-Tocopherol inhibits protein kinase C (PKC) activity, whereas d-beta-tocopherol is ineffective. Furthermore d-beta-tocopherol prevents the inhibition ...
The alpha-tocopherol/cholesterol+ triglyceride ratio was significantly reduced (p<0.05) both in the patients and asymptomatic carriers. The concentrations of the other antioxidants and the lipid peroxides were not different from those of control subjects. The low concentration of plasma alpha-tocopherol...
Is all-rac-alpha-tocopherol different from RRR-alpha-tocopherol regarding cardiovascular efficacy? A meta-analysis of clinical trials. Ann N Y Acad Sci 2004;1031:435-8.Kraemer K, Koch W, Hoppe PP (2004) Is all-rac-α-tocopherol different from RRR-α-tocopherol regarding cardiovascular efficacy...
The team did find a molecule, a vitamin E derivative (衍生物) known as alpha tocopherol, that can stop the cells from dying. “When you damage the photoreceptor cells, they’re damaged for good, so the vitamin E derivative currently just reduces damage,” said Dr Karunarathne. “We’re...

Over a series of hours, the acetate portion of tocopherol acetate slowly seeps into the skin, allowing tocopherol to do its work of protecting against harmful UV rays. The action promotes moisture by removing free radicals and preventing dry skin, which can lead to a visible shedding, or killi...

soluble nutrient with antioxidant properties, alpha-Tocopherol transfer protein (alpha-UP), the product of the gene responsible for familial isolated vitamin E deficiency, plays an important role in maintaining the plasma alpha-tocopherol level by mediating the secretion of alpha-tocopherol by the ...
