Zn-ligation in inorganic deposits in the wall of the human aorta determined by X-ray absorption spectroscopy.
X-ray absorption spectra were recorded at the K edge of Zn from inorganic deposits present in the human aortic wall. The interatomic distances and coordination numbers obtained indicate that Zn atoms probably occupy selected Ca positions in the lattice of the octacalcium phosphate crystals localized at the surface of the deposit.
