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 ...
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 ...
Vitamin E is fat soluble, so dietary supplement products are usually in the form of the vitamin, esterified with acetic acid to generate tocopheryl acetate, and dissolved in vegetable oil in a softgel capsule. [3] For alpha-tocopherol, amounts range from 100 to 1000 IU per serving. Smaller amounts are incorporated into multi-vitamin/mineral ...
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.
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 ...
Vitamin E was named "tocopherol" (from the Greek words tokos, meaning childbirth, and phero, meaning to bring forth) due to its presumed role in aiding conception. Subsequent research identified eight molecules in the vitamin E family, divided into tocopherols and tocotrienols: alpha, beta, delta, and gamma forms. [ 18 ]
