General description

α-Tocopherol is a predominant form of vitamin E in human and animal tissues[1] and also in leaf chloroplasts.[2] It is the major form in supplements.[1] DL-α-Tocopherol acetate is considered as the only storage form of vitamin E.[3]

Application

DL-α-Tocopherol acetate has been used to study it effect on blood pressure and lipidic profile in streptozotocin-induced diabetes mellitus rats.[4] It has also been used as a standard in α-tocopherol analysis using plasma sample[5][6] and mature fresh tobacco leaves.[7]

Packaging

5, 25, 100 g in glass bottle

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.
