Abstract: A method of determining collagen degradation in vivo, including quantitating the concentration of a peptide in a body fluid, the peptide being a C-terminal type II collagen telopeptide containing a hydroxylysyl pyridinoline cross-link or a type III collagen telopeptide containing a hydroxylysyl pyridinoline cross-link. The method includes immunometric assays, fluorometric assays, and electrochemical titrations for quantitation. The structures of specific peptides having cross-links and kits for quantitating these peptides in a body fluid are described.
