Mass spectral envelopes versus H to D HX time for two peptides in apoA-IWT and apoA-IMil that exhibit bimodal HX kinetics (pD 7.3, 5°C). (a, b) Mass spectra at different times of D incorporation of peptide 17–46. (c, d) Mass spectra of peptide 114–126. The bimodal mass spectra were analyzed as described in the legend to Fig. 2.
