  2. γ-Tocotrienol - Wikipedia

    en.wikipedia.org/wiki/Γ-Tocotrienol

    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.

  3. Tocotrienol - Wikipedia

    en.wikipedia.org/wiki/Tocotrienol

    The discovery of tocotrienols was first reported by Pennock and Whittle in 1964, describing the isolation of tocotrienols from rubber. [13] The biological significance of tocotrienols was clearly delineated in the early 1980s, when its ability to lower cholesterol was first reported by Asaf Qureshi and Elson in the Journal of Medicinal Chemistry. [14]

    In addition, the functions of these pigment-protein complexes also change their chemical structure as well. Carotenoproteins that are within the photosynthetic structure are more common, but complicated. Pigment-protein complexes that are outside of the photosynthetic system are less common, but have a simpler structure.

    Studies have actually demonstrated that the two wavelengths together have a synergistic effect on the photosynthetic activity, rather than an additive one. [1] Each photosystem has two parts: a reaction center, where the photochemistry occurs, and an antenna complex, which surrounds the reaction center.

  8. α-Tocopherol - Wikipedia

    en.wikipedia.org/wiki/Α-Tocopherol

    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 ...

  9. Photosynthetic efficiency - Wikipedia

    en.wikipedia.org/wiki/Photosynthetic_efficiency

    Photosynthesis is the only process that allows the conversion of atmospheric carbon (CO2) to organic (solid) carbon, and this process plays an essential role in climate models. This lead researchers to study the sun-induced chlorophyll fluorescence (i.e., chlorophyll fluorescence that uses the Sun as illumination source; the glow of a plant) as ...
