A kinetic study of the reaction between a tocopheroxyl radical and unsaturated fatty acid esters has been undertaken. The rates of allylic hydrogen abstraction from various unsaturated fatty acid esters (ethyl oleate2, ethyl linoleate3, ethyl linolenate4, and ethyl arachidonate5) by the tocopheroxyl radical (5,7-diisopropyltocopheroxyl6) in benzene have been determined spectrophotometrically. The second-order rate constants, k3, obtained are 1.04×10−5 M−1s−1 for2, 1.82×10−2 M−1s−1 for3, 3.84×10…

The chemistry and antioxidant properties of tocopherols and tocotrienols
TLDR
Some possible reasons for the observed differences between the tocopherols (α-, β-, γ-, and δ-) in relation to their interactions with the important chemical species involved in lipid peroxidation, specifically trace metal ions, singlet oxygen, nitrogen oxides, and antioxidant synergists are highlighted.
Kinetic Analysis of Lipid Oxidation Data
TLDR
This chapter reviews knowledge about the mechanism of lipid oxidation and points to gray areas of understanding, and the application of this knowledge to the stability of foods and of lipids in biological compartments is discussed briefly.
