We present a novel model of the inhibition of insulin aggregation using a two-step autocatalytic reaction mechanism with an explicitly competitive inhibition pathway. The kinetic rate constants are estimated using nonlinear regression to analyze previously obtained experimental data for inhibition by synthetic hybrid peptides. This framework provides a method for uniquely characterizing the inhibitory capacity of compounds on protein aggregation.
