Phosphate minerals on Earth, like fluorapatite and whitlockite, take their time to dissolve, they are also not readily incorporated into a water-based solution, which is why their concentration are relatively low.
Burnstein et al performed x-ray diffraction and chemical analyses of six parotid gland stones and found that the three major crystalline components were apatite, magnesium-substituted whitlockite, and octacalcium phosphate.
However, their relevance to biomineralization is clear considering the facts that [alpha]-TCP is easily hydrolyzed to OCP and that the mineral whitlockite, which is found in many biological mineralizations, has a structure very similar to that of [beta]-TCP (28).
