Role of Hydrophobicity on Antioxidant Activity in Lipid

The first investigation of the hydrophobicity influence on antioxidant activity in lipid dispersions took place in the 1950s. Before 1955, a large body of data for the relative effectiveness of antioxidants was generated, and very often it has been extrapolated uncritically from bulk lipids to emulsions, micelles, and membranes in whole tissue

The use and effectiveness of antioxidants in lipids

Twenty-five years ago, Porter, Black, and Drolet (1989) published a milestone article trying to rationalize what makes good antioxidants in lipid-based systems, in particular the influence of hydrophobicity of an antioxidant on its activity through what they called the polar paradox.

Effect of bile acids on lipid peroxidation: the role of iron

This finding suggests that TUDC does not function as an antioxidant per se but may prevent lipid peroxidation caused by TDC. In conclusion, only in the presence of iron ions, hydrophobic bile acids may enhance lipid peroxidation. TUDC has no antioxidant activity per se but may counter the TDC-induced increase in iron-stimulated lipid peroxidation.

relationship between hydrophobicity and antioxidant ability

Relationship between Hydrophobicity and Antioxidant Ability

The polar paradox predicts that hydrophobic antioxidants are more active in emulsions than their hydrophilic homologues, thus assuming a linear dependency between hydrophobicity and antioxidant capacity. In contrast, we formulate in this paper an alternative hypothesis assuming a possible nonlinear dependency. To verify this so-called “nonlinear hypothesis”, the antioxidant capacity of a

Lipid Oxidation | ScienceDirect

This chapter focuses on the versatile role of hydrophobicity on antioxidant capacity in lipid dispersions. This crucial parameter affects both the location and the diffusivity of antioxidants in dispersed lipid systems, which, in turn, impacts their antioxidant capacity.

Role of reverse micelles on lipid oxidation in bulk oils

Hydrophilic Trolox had better antioxidant activity than hydrophobic α-tocopherol. Fluorescence steady state and lifetime decay studies suggests that differences in the antioxidant activity of Trolox and α-tocopherol could be due to differences in their physical location in DOPC reverse micelles.

antioxidant activity of spices and their impact on human

Antioxidant Activity of Spices and Their Impact on Human

Antioxidant activities from the same spices measured by different methods could be correlated. Dragland et al. studied antioxidant activity of several dozen spices, culinary and medicinal (Chinese and Japanese) herbs. They reported that the antioxidant activity of these spices differs by as much as three orders of magnitude.
