D-DELTA-TOCOPHEROL Chemical Properties,Usage,Production

Chemical Properties

clear yellow to brownish viscous liquid

Uses

One of the naturally occurring forms of Vitamin E. Isolated from soybean oil.

Uses

(+)-δ-Tocopherol has been used as a reference material for its extraction from oil using high performance liquid chromatography (HPLC). It has also been used as a standard to quantify δ-tocopherol in soybean using reverse-phase high performance liquid chromatography.

Definition

ChEBI: Delta-tocopherol is a tocopherol in which the chroman-6-ol core is substituted by a methyl group at position 8. It is found particularly in maize (corn) oil and soya bean (soybean) oils. It has a role as a plant metabolite and a food antioxidant. It is a vitamin E and a tocopherol.

General Description

δ-Tocopherol, a homolog of vitamin E, is a phytochemical with potent antioxidant activity. It has been investigated for its potential medical, biological, and physio-chemical applications.

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 fat soluble anti-oxidants that protect cell membranes from oxidative damage. δ-T is methylated at the 8-position. It has an anticancer property. δ-T is involved in proinflammatory response initiated by reactive oxygen species. It lowers lipid accumulation and promotes neuronal differentiation. δ-T also has antiangiogenic and natriuretic activities.
