  2. Hydroxyapatite - Wikipedia

    en.wikipedia.org/wiki/Hydroxyapatite

    Hydroxyapatite (IMA name: hydroxylapatite [5]) (Hap, HAp, or HA) is a naturally occurring mineral form of calcium apatite with the formula Ca 5 (PO 4) 3 (OH), often written Ca 10 (PO 4) 6 (OH) 2 to denote that the crystal unit cell comprises two entities. [6] It is the hydroxyl endmember of the complex apatite group.

    en.wikipedia.org/wiki/Chemical_process_of...

    The human body is composed of approximately: 64% water, 20% protein, 10% fat, 1% carbohydrate, 5% minerals. [1] The decomposition of soft tissue is characterized by the breakdown of these macromolecules, and thus a large proportion of the decomposition products should reflect the amount of protein and fat content initially present in the body. [4]

  4. Apatite - Wikipedia

    en.wikipedia.org/wiki/Apatite

    Apatite is a group of phosphate minerals, usually hydroxyapatite, fluorapatite and chlorapatite, with high concentrations of OH −, F − and Cl − ion, respectively, in the crystal. The formula of the admixture of the three most common endmembers is written as Ca 10 ( PO 4 ) 6 (OH,F,Cl) 2 , and the crystal unit cell formulae of the ...

  5. Amorphous calcium phosphate - Wikipedia

    en.wikipedia.org/wiki/Amorphous_calcium_phosphate

    Amorphous calcium phosphate in combination with casein phosphopeptide has been used as a dental treatment to treat incipient dental decay. ACP sees its main use as an occluding agent, which aids in reducing sensitivity. Studies have shown that it does form a remineralized phase of hydroxyapatite consistent with the natural enamel.

  6. Calcium hydroxyphosphate - Wikipedia

    en.wikipedia.org/wiki/Calcium_hydroxyphosphate

    Calcium hydroxyphosphate (calcium phosphate tribasic, tribasic calcium phosphate, hydroxyapatite, HAp) is an inorganic chemical compound that is made up of calcium, hydrogen, oxygen and phosphorus. Its formula is Ca 5 (OH)(PO 4) 3. [1] It is found in the body and as the mineral hydroxyapatite. [citation needed]

  7. Remineralisation of teeth - Wikipedia

    en.wikipedia.org/wiki/Remineralisation_of_teeth

    P11-4 is a self-assembling β-peptide. It builds a 3-D bio-matrix with binding sites for Calcium-ions serving as nucleation point for hydroxyapatite (tooth mineral) formation. The high affinity to tooth mineral is based on matching distances of Ca-ion binding sites on P11-4 and Ca spacing in the crystal lattice of hydroxyapatite.

  8. Biomineralization - Wikipedia

    en.wikipedia.org/wiki/Biomineralization

    The most common biogenic phosphate is hydroxyapatite (HA), a calcium phosphate (Ca 10 (PO 4) 6 (OH) 2) and a naturally occurring form of apatite. It is a primary constituent of bone, teeth, and fish scales. [33] Bone is made primarily of HA crystals interspersed in a collagen matrix—65 to 70% of the mass of bone is HA.

  9. Cold water extraction - Wikipedia

    en.wikipedia.org/wiki/Cold_water_extraction

    Cold water extraction (also called CWE) is the process whereby a substance is extracted from a mixture via cold water. It is a type of fractional crystallization.. The process generally involves taking a mixture of substances, dissolving them in warm water, and then rapidly cooling the mixture.
