The trifunctional collagen cross-link molecules pyridinoline and deoxypyridinoline have been structurally characterised by (1) low-energy collision-induced dissociation (CID) (E-COM approximate to 15 eV) using Fourier transform ion cyclotron resonance electrospray ionisation mass spectrometry (FT-ICR-ESI-MS), and (2) high-energy collision-induced dissociation (E-COM approximate to 400 eV) using liquid secondary-ion mass spectrometry (LSIMS) on a four-sector mass spectrometer. Both ESI and LSIMS ionisation readily produce the naturally occurring parent cations, although the LSIMS ionisation method is somewhat hampered by background ions from the matrix. Low-energy or high-energy collision-induced dissociation produces structurally informative fragmentations. The observed fragmentation patterns in the low- and high-energy CID spectra are, however, strikingly different. Both low- and high-energy CID are structurally informative and appear to be complementary the characterisation of collagen cross-link molecules. (C) 1977 Elsevier Science B.V.
