What
is D-Alpha Tocopheryl? D-Alpha Tocopheryl is a synthetic form of Vitamin E.
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 which
allows for penetration into biological membranes. Compared to the others,
α-tocopherol is preferentially absorbed and accumulated in humans.
Vitamin
E is found in a variety of tissues, being lipid-soluble, and taken up by the
body in a wide variety of ways. The most prevalent form, α-tocopherol, is
involved in molecular, cellular, biochemical processes closely related to
overall lipoprotein and lipid homeostasis.
Production
of D-Alpha Tocopheryl It is synthesized from a mixture of toluene and
2,3,5-trimethyl-hydroquinone that reacts with isophytol to
all-rac-alpha-tocopherol using iron in the presence of hydrogen chloride gas as
catalyst. The reaction mixture obtained is filtered and extracted with aqueous
caustic soda. Toluene is removed by evaporation and the residue
(all-rac-alpha-tocopherol) is purified by vacuum distillation.
