Description

General description

α-Tocopherol is a predominant form of vitamin E in human and animal tissues and also in leaf chloroplasts. It is the major form in supplements. DL-α-Tocopherol acetate is considered as the only storage form of vitamin E.

Application

DL-α-Tocopherol acetate has been used to study it effect on blood pressure and lipidic profile in streptozotocin-induced diabetes mellitus rats. It has also been used as a standard in α-tocopherol analysis using plasma sample and mature fresh tobacco leaves.

Biochem/physiol Actions

Tocopherols (TCP) (vitamin E) are a series (α, β, γ and δ) of chiral organic molecules that vary in their degree of methylation of the phenol moiety of the chromanol ring. Tocopherols are lipid soluble anti-oxidants that protect cell membranes from oxidative damage. α-Tocopherol is the form of tocopherol preferentially absorbed by homo sapiens. Tocopherol acetate has properties similar but not identical to α-tocopherol.
