2. Hydroxyapatite - Wikipedia

   en.wikipedia.org/wiki/Hydroxyapatite

   Up to 50% by volume and 70% by weight of human bone is a modified form of hydroxyapatite, known as bone mineral. [7] Carbonated calcium-deficient hydroxyapatite is the main mineral of which dental enamel and dentin are composed. Hydroxyapatite crystals are also found in pathological calcifications such as those found in breast tumors, [8] as ...

3. Calcium supplement - Wikipedia

   en.wikipedia.org/wiki/Calcium_supplement

   Microcrystalline hydroxyapatite and ossein-hydroxyapatite are forms of calcium phosphate used as a dietary supplement. [36] Bone meal as a calcium supplementation has largely been discontinued due to concerns of contamination with heavy metals such as lead, arsenic, mercury, and cadmium identified in the 1980s.

4. Artificial bone - Wikipedia

   en.wikipedia.org/wiki/Artificial_bone

   The two major components of bone are hydroxyapatite [Ca10(PO4)6(OH)2], and collagen fibers. Hydroxyapatite, which is one of the most stable forms of calcium phosphate, makes up about 60 to 65 percent of the bone. [5] The rest of the bone is composed of materials including chondroitin sulfate, keratan sulfate and lipid. [5]

5. Discovery and development of bisphosphonates - Wikipedia

   en.wikipedia.org/wiki/Discovery_and_development...

   [7] [8] The bisphosphonates have an intrinsic affinity for the calcium ions (hydroxyapatite) of the bone mineral just as the endogenous pyrophosphates. The difference lies in the non-hydrolysable carbon-phosphorus bond of the bisphosphonates which prevents their metabolism and at the same time ensure an effective absorption from the ...

6. Bone meal - Wikipedia

   en.wikipedia.org/wiki/Bone_meal

   Bone meal (or bonemeal) is a mixture of finely and coarsely ground animal bones and slaughter-house waste products. [1] It is used as a dietary supplement to supply calcium and phosphorus to monogastric livestock in the form of hydroxyapatite. As a slow-release organic fertilizer, it supplies phosphorus, calcium, and a small amount of nitrogen ...

7. Mineralized tissues - Wikipedia

   en.wikipedia.org/wiki/Mineralized_tissues

   The mineral in bone (known as bone mineral) is hydroxyapatite with a lot of carbonate ions, while the organic portion is made mostly of collagen and some other proteins. The hierarchical structural of bone spans across to a three tiered hierarchy of the collagen molecule itself. [ 14 ]
