Tocotrienols are named by analogy to tocopherols (from Greek words meaning to bear a pregnancy (see tocopherol); but with this word changed to include the chemical difference that tocotrienols are trienes, meaning that they share identical structure with the tocopherols except for the addition of the three double bonds to their side chains.
The binding site for RRR-α-tocopherol is a hydrophobic pocket with a lower affinity for beta-, gamma-, or delta-tocopherols, or for the stereoisomers with an S configuration at the chiral 2 site. Tocotrienols are also a poor fit because the double bonds in the phytic tail create a rigid configuration that is a mismatch with the α-TTP pocket. [14]
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 ...
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 ...
γ-Tocotrienol is one of the four types of tocotrienol, a type of vitamin E. [ 1 ] [ 2 ] Vitamin E exists in nature in eight forms, each of which consists of a head section joined to either a saturated ( phytyl ) or an unsaturated ( farnesyl ) tail.
γ-Tocopherol (gamma-tocopherol) is a tocopherol and one of the chemical compounds that comprise vitamin E. As a food additive, it has E number E308. See also
