what disorder primary affects the bone matrix and is due to the loo of calcium salt
There are two that are more common: osteopenia ("little bone") and osteoporosis ("bone with holes"). These two are common as you age.
Calcium is found in the matrix of bone.
Many things do but the best example is bone with a matrix made mostly of calcium.
Calcium
Bone matrix is composed mostly of calcium, phosphorus, and trace minerals like iron, copper, and magnesium.
Osseous tissue has cells that are arranged in concentric circles around a nutrient canal matrix and is hard due to calcium salts.
It is composed primarily of hyaluronic acid.
Bone cells that liquefy the bone matrix and release calcium into the blood are called Osteoclasts. Immature or matrix depositing bone cells are called osteoblasts.
Cal Apatite is a comprehensive bone support formula featuring purity-tested, calcium-rich MCHC†, a complex crystalline compound composed primarily of calcium, phosphorus, delicate organic factors and protein matrix, bone-derived growth factors, and a full spectrum of trace minerals that naturally comprise healthy bone.*
Because of the hard calcium salts in the matrix
The bone matrix is hard due to the primary salt of calcium chloride.
The extracellular matrix consists primarily of calcium and phosphorus in the form of hydroxyapatite, Ca10(PO4)6(OH)2.
