Effect of Temperature, Cholesterol Content, and Antioxidant Structure on the Mobility of Vitamin E Constituents in Biomembrane Models Studied by Laterally Diffusion-Controlled Fluorescence Quenching

Kinetic parameters relevant for the antioxidant activity of the vitamin E constituents (α, β, γ, and δ homologues of tocopherols and tocotrienols) and of an amphiphilic vitamin C derivative, l-ascorbyl 6-palmitate, were determined. Fluorescence quenching experiments of 2,3-diazabicyclo[2.2.2]oct-2-e...
