EICs of C-telopeptide galactosyl-pyridinoline species containing helical residues α1- and α2-87 (A) and C-telopeptide-based Pyr and pyrrole (B). The EICs were generated for the most abundant charge state (6+) of the most abundant glycoforms (G-Pyr and G-pyrrole, respectively) observed in the chymotryptic digest of fraction F1/P1 collected after molecular sieve chromatography.
