There is a clear association between proteoglycans and apatite crystals when bone mineralisation takes place in cartilage. However, the proteoglycan content in the cartilage falls during bone formation. WebChemical analysis has shown that bone mineral contains about 5% CO3 and about 5–10% HPO 4. With time the Ca/P ratio increases to values approaching that of pure apatite …

WebBasic Biology of Bone. Bone is a composite tissue consisting of mineral, matrix (collagen and non-collagenous proteins), cells, and water. The mineral is hydroxyapatite, which is an analog of the naturally occurring … WebApr 2, 2009 · History. The structure of the Ca–P solid phase in bone was first identified by deJong in 1926 as a crystalline calcium phosphate similar to geological apatite by chemical analyses and, most importantly, by X-ray diffraction [ 1 ]. The X-ray diffraction data was confirmed a few years later [ 2 ]. Fig. 1. X-ray diffractometer patterns obtained ...
WebTo 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.
