Bone
The primary chemical present in limestone is calcium carbonate (CaCO3).
The primary constituents of Earth's atmosphere are nitrogen (78%), oxygen (21%), argon (0.93%), and trace amounts of carbon dioxide, neon, helium, and other gases. Water vapor is also present, with variable concentrations depending on location and weather conditions.
A 10% solution of calcium nitrate has a pH of about 6.0. Calcium nitrate is the primary source of water soluble calcium in hydroponics. Prolonged use in other growing media can result in a gradual increase in pH because the negatively charged nitrate ions are taken up faster than the positively charged calcium ions.
Calcite is the primary mineral found in dripstone formations such as stalactites and stalagmites. It is a common form of limestone that is formed from the precipitation of calcium carbonate dissolved in water.
Detrital sedimentary rocks are classified based on the particle size of the grains they contain. These rocks include conglomerate, sandstone, and shale, with conglomerate having the largest particles, followed by sandstone and shale with finer particles. The size of particles in a detrital sedimentary rock can provide information about the environment in which the rock was formed.
The bone matrix is hard due to the primary salt of calcium chloride.
Hydroxyapatite is inorganic. Its chemical structure contains no carbon at all.
Osteoid is the organic component of bone tissue, primarily composed of collagen. Hydroxyapatite is a mineral component of bone tissue, providing strength and hardness to the bone. Osteoid contributes to the flexibility of bones, while hydroxyapatite enhances their structural integrity. Together, they give bones their rigidity and resistance to fractures.
Hydroxyapatite is a naturally occurring mineral form of calcium apatite. It is the primary mineral component of vertebrate bone and tooth enamel. In medical and dental applications, hydroxyapatite is used as a biomaterial for bone tissue repair and regeneration.
The primary mineral found in bone matrix is hydroxyapatite, a crystalline form of calcium phosphate. It gives bone its strength and rigidity by providing a framework for bone structure.
The extracellular matrix consists primarily of calcium and phosphorus in the form of hydroxyapatite, Ca10(PO4)6(OH)2.
Yes, bone is a composite material made up of two primary components: organic matrix, mainly collagen fibers, and inorganic mineral crystals, primarily hydroxyapatite. This unique combination gives bone its strength and resilience.
The two primary substances associated with healthy bones are both Calcium and Vitamin D.
Enamel is over 95 per cent mineral. The principle mineral is hydroxyapatite which is a naturally occurring form of calcium phosphate. The remaning 5% is organic consisting of proteins called enamelins, amelogenins and albumin.
Osteoid-producing osteoblasts rely primarily on the rough endoplasmic reticulum (rER) to produce primary structures such as collagen and calcium-binding proteins. The rER is essential for the synthesis of proteins, including the collagen matrix that provides structural support for bone. Additionally, this organelle is involved in post-translational modifications, ensuring that the proteins are properly folded and functional for bone mineralization.
The primary substance responsible for the strength and hardness of bones is hydroxyapatite, which is a crystalline mineral compound made of calcium and phosphate. This mineral gives bones their rigidity and ability to withstand mechanical stress.
From Wikipedia, "Hydroxylapatite, also called hydroxyapatite (HA), is a naturally occurring mineral form of calcium apatite with the formula Ca5(PO4)3(OH), but is usually written Ca10(PO4)6(OH)2 to denote that the crystal unit cell comprises two entities".
