Natural-abundance 43Ca solid-state NMR spectroscopy of bone.

ABSTRACT: Structural information about the coordination environment of calcium present in bone is highly valuable in understanding the role of calcium in bone formation, biomineralization, and bone diseases like osteoporosis. While a high-resolution structural study on bone has been considered to be extremely challenging, NMR studies on model compounds and bone minerals have provided valuable insight into the structure of bone. Particularly, the recent demonstration of (43)Ca solid-state NMR experiments on model compounds is an important advance in this field. However, application of (43)Ca NMR is hampered due to the low natural-abundance and poor sensitivity of (43)Ca. In this study, we report the first demonstration of natural-abundance (43)Ca magic angle spinning (MAS) NMR experiments on bone, us
