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 ...
The World Health Organization does not have any recommendations for food fortification with vitamin E. [56] The Food Fortification Initiative does not list any countries that have mandatory or voluntary programs for vitamin E. [57] Infant formulas have alpha-tocopherol as an ingredient. In some countries, certain brands of ready-to-eat cereals ...
Tocopherols (/ t oʊ ˈ k ɒ f ə ˌ r ɒ l /; [1] TCP) are a class of organic compounds comprising various methylated phenols, many of which have vitamin E activity. Because the vitamin activity was first identified in 1936 from a dietary fertility factor in rats, it was named tocopherol, from Greek τόκος tókos 'birth' and φέρειν phérein 'to bear or carry', that is 'to carry a ...
As part of their adaptation from marine life, terrestrial plants began producing non-marine antioxidants such as ascorbic acid (), polyphenols, and tocopherols.The evolution of angiosperm plants between 50 and 200 million years ago resulted in the development of many antioxidant pigments – particularly during the Jurassic period – as chemical defences against reactive oxygen species that ...
The CDC's findings were based on fluid samples from the lungs of 29 patients with vaping-associated pulmonary injury, which provided direct evidence of vitamin E acetate at the primary site of injury in all the 29 lung fluid samples tested. [3] Research suggests when vitamin E acetate is inhaled, it may interfere with normal lung functioning. [5]

The vitamin E family comprises four tocotrienols (alpha, beta, gamma, delta) and four tocopherols (alpha, beta, gamma, delta). The critical chemical structural difference between tocotrienols and tocopherols is that tocotrienols have unsaturated isoprenoid side chains with three carbon-carbon double bonds versus saturated side chains for ...
