Structure and Chemistry of Bone Mineral

Abstract

Many of the properties unique to the calcified tissues of vertebrates can be ascribed to the mineral salts investing the interstitial spaces of these structures. By far the most distinctive of these properties, hardness, can be attributed directly to the ultra-structural interrelations between the mineral and the organic, fibrous extracellular matrix. To many, however, this hardness implies inertness and passivity, especially of the mineral component itself. But, the mineral salts of bone are far from chemically inactive, for in addition to their mechanical function, these salts play an important role in the dynamic physiological chemistry of living hard tissue. It is this dual mechanical and physiological character that makes the study of the mineral component of bone a fascinating subject; and it is challenging to try to understand how the mineral can fulfill its two disparate, yet complementary roles. This chapter will attempt to summarize the most recent progress in the description of this component and to review the current concepts concerning its origin and its physiological-structural functions. Emphasis will be placed on the mineral itself, alluding to the organic and cellular components only in reference to their involvement in the formation, maintenance, and function of the mineral component.
