Tocotrienols are plant-derived natural products belonging to the vitamin E family of diterpenoids. They exist as four isomers (alpha, beta, gamma, delta), each differing in the number and position of methyl groups on their chromanol ring.
Tocotrienols extracted from plants are always dextrorotatory stereoisomers, signified as d-tocotrienols. In theory, levorotatory forms of tocotrienols (l-tocotrienols) could exist as well, which would have a 2S rather than 2R configuration at the molecules' single chiral center, but unlike synthetic dl-alpha-tocopherol, the marketed tocotrienol ...
Naturally occurring vitamers of vitamin E include tocopherols (α-, β-, γ-, and δ-) and tocotrienols ( α-, β-, γ-, and δ-). Many plant-based foods provide all eight naturally occurring vitamers of vitamin E in varying amounts from different sources. Tocopherols are more abundant in commonly consumed foods relative to tocotrienols.
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.
Vitamin E, including tocotrienol and tocopherol, is fat soluble and protects lipids. Sources include wheat germ, seabuckthorn, nuts, seeds, whole grains, green leafy vegetables, kiwifruit, vegetable oil, and fish-liver oil. Alpha-tocopherol is the main form in which vitamin E is consumed.
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 ...
α-Tocotrienol is a form of tocotrienol and one of the chemical compounds that is considered vitamin E. See also. β-Tocotrienol; γ-Tocotrienol; δ-Tocotrienol;
A melting pot of Indonesian flora in Cibodas botanical garden, Indonesia. The flora consists of many unique varieties of tropical plants. Blessed with a tropical climate and roughly 17,000 islands, Indonesia is the nation with the second highest biodiversity in the world.
