Experimental research on the chemical composition of hydroxyapatite in bones

Popis výsledku v původním jazyce

In the mineral structure of OHAp numerous substitutions may occur which cause changes in physical processes in OHAp. Bioapatite in fossil teeth and bone tissue can be highly affected by the character of natural environment, especially by the mineralogy,geochemistry, and hydrology of the rock background. Dissected samples of turtle humerus (Testudo graeca) were used for experiment. Several samples of bone tissue remained with collagen, while the other were deproteinated. Numerous simulation experimentswere realised (fresh samples vs. deproteinated samples immersed in solutions of Ba, Sr and Zn) to determine the ability of selected elements to incorporate in the bone tissue and/or the structure of bioapatite. The samples were analysed by the method ofelectron microprobe and X-ray diffraction. The crystallinity of deproteinated bone is slightly higher due to the lower content of organic components (e.g. collagen).
