  2. 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.

  3. 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 ...

  4. Artificial bone - Wikipedia

    en.wikipedia.org/wiki/Artificial_bone

    Artificial bone refers to bone-like material created in a laboratory that can be used in bone grafts, to replace human bone that was lost due to severe fractures, disease, etc. [1] Bone fracture, which is a complete or partial break in the bone, is a very common condition that has more than three million US cases per year. [ 2 ]

  5. Bone health - Wikipedia

    en.wikipedia.org/wiki/Bone_health

    Bone Mineral Density (BMD) tends to peak at a young age. When children are younger, they start building up their BMD through their nutrition and through exercise. BMD peaks at around 12.5 years old for girls and around 14 years old for boys. [23] It could be caused by a deficiency in calcium or Vitamin D. Calcium is the main nutrient for bone ...

  6. 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 ]

  7. Calcium metabolism - Wikipedia

    en.wikipedia.org/wiki/Calcium_metabolism

    Calcium metabolism is the movement and regulation of calcium ions (Ca 2+) in (via the gut) and out (via the gut and kidneys) of the body, and between body compartments: the blood plasma, the extracellular and intracellular fluids, and bone.

  8. Bioactive glass - Wikipedia

    en.wikipedia.org/wiki/Bioactive_glass

    Mineralization in which the calcium phosphate layer gradually transforms into crystalline hydroxyapatite, that mimics the mineral phase naturally contained with vertebrate bones. Later, it was discovered that the morphology of the gel surface layer was a key component in determining the bioactive response.

  9. Osteoblast - Wikipedia

    en.wikipedia.org/wiki/Osteoblast

    The skeleton, often referred to as the skeletal system, is important both as a supporting structure and for maintenance of calcium, phosphate, and acid-base status in the whole organism. [5] The functional part of bone, the bone matrix, is entirely extracellular. The bone matrix consists of protein and mineral.
