At room temperature, α-tocopheryl acetate is a fat-soluble liquid. It has 3 chiral centers and thus 8 stereoisomers. It is made by esterifying α-tocopherol with acetic acid. 2R,4R,8R-isomer, also known as RRR-α-tocopheryl acetate, is the most common isomer used for various purposes. This is because α-tocopherol occurs in nature primarily as ...
α-tocopheryl acetate, an acetate ester of α-tocopherol . Manufacturers also commonly convert the phenol form of the vitamins (with a free hydroxyl group) to esters, using acetic or succinic acid. These tocopheryl esters are more stable and are easy to use in vitamin supplements. α-Tocopheryl esters are de-esterified in the gut and then ...
α-Tocopherol (alpha-tocopherol) is a type of vitamin E.Its E number is "E307". Vitamin E exists in eight different forms, four tocopherols and four tocotrienols.All feature a chromane ring, with a hydroxyl group that can donate a hydrogen atom to reduce free radicals and a hydrophobic side chain, along with an aromatic ring is situated near the carbonyls in the fatty acyl chains of the ...
An example SDS, including guidance for handling a hazardous substance and information on its composition and properties. A safety data sheet (SDS), [1] material safety data sheet (MSDS), or product safety data sheet (PSDS) is a document that lists information relating to occupational safety and health for the use of various substances and products.

Both natural and synthetic tocopherols are subject to oxidation, so dietary supplements are esterified, creating tocopheryl acetate for stability purposes. [ 3 ] [ 7 ] Population studies have suggested that people who consumed foods with more vitamin E, or who chose on their own to consume a vitamin E dietary supplement , had lower incidence of ...
α-Tocopheryl palmitate is the palmitate ester of α-tocopherol and is a form of vitamin E. [ 1 ] [ 2 ] Related compounds include α-tocopheryl acetate and α-tocopheryl succinate . See also
Fortified foods and dietary supplements predominantly contain vitamin E as α-tocopherol salts, most frequently as tocopheryl acetate or vitamin E acetate. [ 2 ] The different naturally occurring vitamers of vitamin E are not interconverted in the body and have different metabolic effects.
