Application

(+)-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.

Actions biochimiques/physiologiques

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. Various isofroms and analogues of tocopherol have opposing and differentiated regulatory activities in vivo.
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.
