NettetIn the linoleic acid peroxidation assay, both fractions inhibited the formation of lipid peroxide with F5 being more active than F7. These fractions can be further tested for their ability to retard lipid oxidation in food systems. NettetTholstrup T, Raff M, Straarup EM, Lund P, Basu S, Bruun JM. An oil mixture with trans-10, cis-12 conjugated linoleic acid increases markers of inflammation and in vivo lipid peroxidation compared with cis-9, trans-11 conjugated linoleic acid in postmenopausal women. J Nutr. 2008;138(8):1445–1451. 16.
NettetIn this assay, ABTS + is preprepared by oxidation with potassium persulfate. Ferric Reducing Ability of Plasma Ferric reducing ability of plasma (FRAP) is based on the reduction of a colored ferric complex to ferrous ion at low pH, causing the colored ferrous tripyridyltriazine complex to form.

NettetLinoleic acid (30 μM) increases migration of IEC-6 rat intestinal epithelial cells in a wound healing assay. 2 Rats fed a linoleate-deficient diet exhibit decreased body weight and an increased ratio of eicosatrienoate to arachidonate in liver and serum phospholipids compared with rats fed a control diet, as well as mild scaling of forepaw skin. 3 Nettetof double bonds in linoleic acid hydroperoxides during the early phases of peroxidation. With increasing lipid peroxidation, lipid hydroperoxides decompose to dimin-ish 234 nm absorbance. TBA measures the coloured pig-ment formed following condensation between TBA and malonaldehyde, a product of more extensive fatty acid oxidation.
