Description

(+)-α-Tocopherol is a vitamin E derivative. vitamin E is a fat-soluble antioxidant.

α-Tocopherol (phenyl-5,7-dimethyl-d6) is the most bioactive form of fat-soluble vitamin E, which has a stable deuterium label, can be used as an internal standard for chromatographic methods with a tandem mass spectrometric detector.

light yellow liquid

VITAMIN E is sometimes referred to as the antisterility vitamin, factor X (an earlier designation), chemically vitamin E is alphatocopherol. Active analogues and related compounds include: dl-α-Tocopherol; 1-α-tocopherol; esters (succinate, acetate, phosphate), and β, ζ 1, ζ 2- tocopherols. The principal physiological forms are D-a-tocopherol, tocopheronolactone, and their phosphate esters.

ChEBI: An alpha-tocopherol that has R,R,R configuration. The naturally occurring stereoisomer of alpha-tocopherol, it is found particularly in sunflower and olive oils.

Drug Information

Health Hazards：

The physiological functions of vitamin E substances include: (1) bio logical antioxidant; (2) normal growth maintenance; (3) protects unsaturated fatty acids and membrane structures; (4) aids intestinal absorption of unsaturated fatty acids; (5) maintains normal muscle metabolism; (6) maintains integrity of vascular system and central nervous system; (7) detoxifying agent; and (8) maintains kidney tubules, lungs, genital structures, liver, and red blood cell membranes.In livestock and laboratory animals, a deficiency of vitamin E substances may cause degeneration of reproductive tissues, muscular dystrophy, encephalomalacia, and liver necrosis. Considerable research is required to fully determine supplementation of livestock diets unless typical symptoms of a deficiency appear. Symptoms have appeared where there are selenium deficiencies in the soil and where there are excessive levels of nitrates in the soil. “White muscle” is the term used to describe a condition of muscular dystrophy in cattle.

D-α-Tocopherol Use and Manufacturing

α-Tocopherol is the most bioactive of the naturally occurring forms of Vitamin E. Richest sources are green vegetables, grains, and oils, particularly palm, safflower and sunflower oils.
