Insulin fibrillation kinetics at different concentrations of EGCG, di-C7-PC and methylglyoxal (points) and fittings to equation ( 1 ) (surface). X: aggregation data measured by absorbance at 600 nm (AU), ThT fluorescence intensity at 482 nm (AU) or ThT fluorescence intensity (%). A: experimental data of EGCG obtained at pH = 2.0 and T = 60°C. B: experimental data of EGCG obtained at pH = 7.4 and T = 37°C. C: di-C7-PC data. D: methylglyoxal data.
