Description

clear light brown viscous liquid

Clear, viscous, pale yellow oil which oxidises and darkens on exposure to air or light|Solid

Gamma-tocopherol is a tocopherol in which the chroman-6-ol core is substituted by methyl groups at positions 7 and 8. It is found particularly in maize (corn) oil and soya bean (soybean) oils. It has a role as a plant metabolite, a food antioxidant and an algal metabolite. It is a vitamin E and a tocopherol.|gamma-Tocopherol is under investigation in clinical trial NCT00836368 (In Vitro Basophil Responsiveness to Allergen Challenge After Gamma-tocopherol Supplementation in Allergic Asthmatics).|Gamma-Tocopherol is the orally bioavailable gamma form of the naturally-occurring fat-soluble vitamin E, found in certain nuts and seeds, with potential antioxidant activity. Although the exact mechanism of action of this tocopherol has yet to be fully identified, gamma-tocopherol appears to have the ability to scavenge free radicals, thereby protecting against oxidative damage.|A natural tocopherol with less antioxidant activity than ALPHA-TOCOPHEROL. It exhibits antioxidant activity by virtue of the phenolic hydrogen on the 2H-1-benzopyran-6-ol nucleus. As in BETA-TOCOPHEROL, it also has three methyl groups on the 6-chromanol nucleus but at different sites.
