Is there a "citrate-apatite" in biological calcified systems?
An apatite containing citrate ions has been synthesized. Measurements of specific surface, as well as Ca/P ratio, infrared, X-ray, and calcination data are all consistent with the idea that citrate ion substitutes for PO4(3-) ion on the apatitic surface.
