Merck, T1782-25MG, (+)-γ-Tocopherol

Application
(+)-γ-Tocopherol has been used:
as reference material for the quantification of γ-tocopherol in the oil sample using high performance liquid chromatography with diode array detector (HPLC/DAD)(192}
as a component of diet to feed vitamin-E-depleted rats to study its effects
as an additive in the feed to study its effects in reducing dietary induced oxidative stress in vivo and improving meat lipid stability in broilers

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 antioxidants 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.
