title: High-resolution solid-state nuclear magnetic resonance spectra of dentin collagen.
abstract: Insoluble collagen of bovine dentin was characterized by high-resolution solid-state 13C nuclear magnetic resonance (NMR) spectroscopy using a cross-polarization magic angle spinning procedure. A downfield shift was observed in the signal of hydroxyproline C beta compared with that in skin collagen, indicating a distortion in the hydroxyproline structure. A signal of 31P NMR was detected in dentin collagen that was compatible with the presence of matrix-associated phosphoprotein.
