Adsorption Properties of Phospho-Polypeptide on Synthetic Hydroxyapatite Biomaterials

摘要

This article dealt with the effect of phosphorylated peptides and peptides onto hydroxyapatite(HAP) biomaterials by considering their influence when they were present at the synthetic HAP interface. The adsorption isotherms adequately fitted the Langmuir shape, and from the comparision between two different adsorbates, the results of the investigation indicated that the phosphate group greatly enhanced the adsorption affinity. The results obtained layed the solid foundation for further research on the regulating function of phosphorylated amino acids with hydroxyapatite biological composites.
