Extracellular Matrix of Osseous Tissue Bony material is actually a composite material composed of approximately 1/3 organic and 2/3 inorganic matter. The organic matter is composed of collagen, glycosaminoglycans , proteoglycans and glycoproteins. The inorganic matter is mostly hydroxyapatite which is crystallized calcium phosphate. The remainder of the inorganic material is calcium carbonate (10%) and trace amounts of other minerals (fluoride, sulfate, potassium, magnesium).
