High-resolution 13C NMR spectra of 15 samples of uncomplexed and metalcomplexed tetranactin and nonactin were recorded in the solid state, revealing characteristic displacements of peaks due to complex formation and the effect of crystalline packing on the 13C chemical shifts and spidattice relaxati
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
