a)The observed changes in proximity to the N-terminus (solid lines) and the C-terminus (dashed lines) in mobile (blue) and partially mobile (red) based on the observed amount of neutral loss displayed by a peptide. b) Distribution of neutral loss in b-ions derived from 37 peptides with acetylated N-terminii. c) Spectrum of doubly protonated AQISpSPNLR. Red markers with the ion series denoted (x+2)indicate ions annotated as the x-type ions that have been reported as markers of oxazoline or macrocycle formation.
