摘要：

The basis for transphosphorylation between nucleotides and hydroxyapatite (HA) has been explored. Using a recently-proposed model for the surface of HA and the structure of 2- and 3-membered polyphosphates, a reasonable atomic explanation can be shown for this reaction. Transphosphorylation has been found to result in a pyrophosphate on HA which is distinctive from pyrophosphate absorbed onto HA from solution. The models suggest that this distinction is due to a different orientation of the pyrophosphate on the surface of the HA depending on the origin of the pyrophosphate. © 1969 Springer-Verlag.
