Figure 6. ABAP-induced BTBE and tyrosine oxidation.
Panel A: (a) BTBE (0.3 mM)-containing DLPC liposomes in sodium phosphate100 mM (pH 7.3) plus 0.1 mM DTPA were exposed to (b) ABAP (20 mM) in the absence and (c) presence of nitrite (40 mM) and 3-nitro-BTBE and 3,3´-di-BTBE were measured. Panel B: (a) Tyrosine (0.3 mM) in sodium phosphate 100 mM (pH 7.3) plus 0.1 mM DTPA was exposed to (b) ABAP (20 mM) in the absence and (c) presence of nitrite (40 mM) and 3-nitrotyrosine and 3,3´-dityrosine were measured.
