Dec 4, 2024 · Bone - Calcium, Phosphate, Hardness: Depending upon species, age, and type of bone, bone cells represent up to 15 percent of the volume of bone; in mature bone in most higher animals, they usually represent only up to 5 percent.
Bone - Wikipedia
Bones consist of living cells (osteoblasts and osteocytes) embedded in a mineralized organic matrix. The primary inorganic component of human bone is hydroxyapatite, the dominant bone mineral, having the nominal composition of Ca 10 (PO 4) 6 (OH) 2. [28]
Composition of the human body - Wikipedia
Body composition may be analyzed in various ways. This can be done in terms of the chemical elements present, or by molecular structure e.g., water, protein, fats (or lipids), hydroxyapatite (in bones), carbohydrates (such as glycogen and glucose) and DNA.
Bone mineral: update on chemical composition and structure
These findings initiated a flurry of research on a more detailed chemical composition and crystal structure of both geological and synthetic apatites and of bone mineral, initially carried out principally by geologists, crystallographers and chemists, but later by biochemists and physiologists because of the clear potential of this new ...
Structure and composition of bone - DoITPoMS
Composition. Bone itself consists mainly of collagen fibres and an inorganic bone mineral in the form of small crystals. In vivo bone (living bone in the body) contains between 10% and 20% water. Of its dry mass, approximately 60-70% is bone mineral.
Bone composition: relationship to bone fragility and …
The composition of a bone can be described in terms of the mineral phase, hydroxyapatite, the organic phase, which consists of collagen type I, noncollagenous proteins, other components and water. The relative proportions of these various components ...
Bone | Definition, Anatomy, & Composition | Britannica
Dec 4, 2024 · bone, rigid body tissue consisting of cells embedded in an abundant hard intercellular material. The two principal components of this material, collagen and calcium phosphate, distinguish bone from such other hard tissues as chitin, enamel, and shell.
Bone mineral: new insights into its chemical composition
Jun 11, 2019 · Bone is a natural composite material whose main components are mineral and organic matrices 1, 2. The mature mineral matrix is in the form of nanosized, elongated platelet-like carbonated calcium...
Chemical and Biochemical Basis of Cell-Bone Matrix Interaction in ...
Bone, a calcified tissue composed of 60% inorganic component (hydroxyapatite), 10% water and 30% organic component (proteins), has three functions: providing mechanical support for locomotion, protecting vital organs, and regulating mineral homeostasis.
