Protein matrix of bone

WebbAs bone synthesis proceeds, the osteoblast becomes completely surrounded by matrix referred to as osteoid, and when that matrix becomes mineralized the encased cell is referred to as an osteocyte. Gene and molecular controls of osteoblast differentiation and the structural molecules synthesized by osteoblasts are reviewed in Sections IX and X. WebbIts main components are calcium carbonate, β-chitin, and shell matrix proteins, with a complex “wall-septa” microstructure. − At present, most of the cuttlebones are discarded …

The skeleton is a large organ that is formed and degraded throughout life in the air-breathing vertebrates. 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. The functional part of bone, the bone matrix, is entirely extracellular. The bone matrix consists of protein and mineral. The protein forms the organic matrix. It is synthesized and then t… lagged trump on top https://xavierfarre.com
