摘要
骨磷灰石晶体的化学组成、晶体结构和短程有序对骨的生理和结构功能起着重要作用,但骨矿物晶体是否含有OH-存在多年的争论,以及B型碳酸盐磷灰石中碳酸根替换的精确位置仍没有完全弄清。本文综述了生物磷灰石矿物的成分和晶体结构方面的最新研究进展。介绍了运用广泛的化学分析方法和光谱技术研究骨矿物晶体中OH-存在形式。讨论了碳酸根离子在磷灰石晶体中的A型和B型替换。更深入地探讨了生物磷灰石稳定性、替代机制及许多表面现象。
The chemical composition, crystal structure, and short-range order of apatite crystals of bone play an essential role in the biological and structural functions of bone substance. However, the question of the apatite crystals of bone contain hydroxyl ion remains, and the crystal structure of carbonated apatite still remains subject to uncertainties since the exact location of carbonate ions has not yet been determined. This review aims at current developments in biological apatite mineral components and their crystal structures. It introduces near-absence of OH- in bone apatites has been established through extensive study by chemical analyses and spectroscopy techniques, and discusses both the A-site and B-site substitution of carbonate ions in the apatite structures. It is anticipated to provide a deeper understanding about stability, mechanisms of substitution and many surface phenomena of biological apatite.
