Figure 2. Effect of 4-NC (filled circles) and α-tocopherol (open circles) on MDA production in egg PC vesicles oxidized with AAPH (A) or FeSO4+H2O2 (B). Egg PC vesicles (1.6 mM) were incubated with several concentrations of 4-NC for 1.5 h at 37°C. Lipid peroxidation was initiated by a 3-h incubation with 30 mM AAPH at 37°C or a 1-h incubation with 0.1/1 mM FeSO4/H2O2 at 37°C. 4-NC: 4-nerolidylcatechol; MDA: malondialdehyde; AAPH: 2,2′-azobis(2-aminopropane) hydrochloride; PC: phosphatidylcholine.
