We have recorded high-resolution l3C-nmr spectra of collagen fibrils in the solid state by the cross-polarization-magic-angle-spinning (CP-MAS) method and analyzed the spectra with reference to those of collagenlike polypetides. We used two kinds of model polypeptides to obtain reference 13C chemica
