Highly explanatory SEM models were obtained for the traditional collagen quality indicators (collagen yield, C, N, CN), but no relationship was found between quality and δ13C and δ15N ratios. The observed decrease in C and N content and increase in CN ratios is controlled by the degradation of protein backbone components and the relative preservation of carbon-rich compounds, proteoglycans and, to a lesser extent, aliphatic moieties. Our results suggest that FTIR-ATR is an ideal technique for collagen characterization/pre-scr
