Comments In minerals as well as in solution, calcium occurs predominantly in a complex form, mostly as calcium phosphate (e.g. hydroxyapatite [Ca10(PO4)6(OH)2]), which makes up 60% of the weight of human skeleton, that is, the skeleton of a man contains 1.0 to 1.3 kg of calcium, that of a woman 0.8 to 0.9 kg, comprising 99% of the total calcium of a human body.
