title: [Study on calcium-cholate-phosphate ternary complexes by FTIR spectroscopy].
abstract: The aim of this paper was to examine the calcium-cholate-phosphate tenary complexes by FTIR spectroscopy. The results indicated that the mole ratio of cholate to phosphate were 1:3 and 1:4 in ternary complexes respectively when the initial mole ratio of cholate to phosphate were 3:1 and 1.5:1 in reaction. The FTIR spectroscopic results demonstrated that in the ternary complexes Ca2+ was coordinated with O in both COO- and PO(4)3- groups.
