Dependence between lines width of ¹H and 31P, amount of the organic matrix and a degree of the apatite crystallinity is established in a calf bone by MAS NMR method. A scheme for organic mineral complex formation of the bone was proposed. It is based on hydrogen bonds formation between protons of OH-groups and carbonyl ions of oxygen of collagen peptide groups. It was established in the IR method, that both replacements of A-(OH-→CO32- ) and B-(POH4³→CO32- ) types have place in bone apatite. [ABSTRACT FROM AUTHOR] |
