NCIt related terms : .ALPHA.-TOCOPHEROL; 2,5,7,8-tetramethyl-2-(4,8,12-trimethyltridecyl)chroman-6-ol;
NCIt definition : The orally bioavailable alpha form of the naturally-occurring fat-soluble vitamin
E, with potent antioxidant and cytoprotective activities. Upon administration, alpha-tocopherol
neutralizes free radicals, thereby protecting tissues and organs from oxidative damage.
Alpha-tocopherol gets incorporated into biological membranes, prevents protein oxidation
and inhibits lipid peroxidation, thereby maintaining cell membrane integrity and protecting
the cell against damage. In addition, alpha-tocopherol inhibits the activity of protein
kinase C (PKC) and PKC-mediated pathways. Alpha-tocopherol also modulates the expression
of various genes, plays a key role in neurological function, inhibits platelet aggregation
and enhances vasodilation. Compared with other forms of tocopherol, alpha-tocopherol
is the most biologically active form and is the form that is preferentially absorbed
and retained in the body.;
Alternative definition : CRCH: Tocopherol with three methyl groups on its chromanol ring.;
