General description

α-Tocopherol is a form of vitamin E. Vitamin E can be obtained through dietary sources. RRR‐α‐tocopherol is a natural form of α-Tocopherol.

application

DL-alpha-Tocopherol acetate was used as a vitamin E supplement for studying whether the addition of an antioxidant or vitamin E in the diet of rats with dextran sulfate sodium (DSS)-induced colitis can reduce detrimental impact of inflammatory bowel disease.

Biochem/physiol Actions

α-Tocopherol is also known as a radical-chain breaker due to its anti-oxidant property.
Tocopherols are lipid soluble anti-oxidants that protect cell membranes from oxidative damage. α-Tocopherol is the form of tocopherol preferentially absorbed by Homosapiens. DL-α-Tocopherol acetate can inhibit oxidation of linoleate.

Inflammatory bowel disease is often associated with iron deficiency anemia and oral iron supplementation may be required. However, iron may increase oxidative stress through the Fenton reaction and thus exacerbate the disease. This study was designed to determine in rats

The formation of alpha-tocopherol--lipoxygenase complex was elucidated using immobilized affinity purified soybean lipoxygenase and [D-3H]alpha-tocopherol. The alpha-tocopherol--lipoxygenase complex did not dissociate on addition of linoleic acid. Iodoacetate modified immobilized lipoxygenase did not form the complex with alpha-tocopherol.
