Calcium Phosphate Tribasic
AAA
Tricalcium phosphate is a compound with formula Ca3(PO4)2. It is also known as calcium orthophosphate, tertiary calcium phosphate, tribasic calcium phosphate, or "bone ash" (calcium phosphate being one of the main combustion products of bone). It has an alpha an alpha' and a beta crystal form, the alpha state being formed at high temperatures. As rock, it is found in Whitlockite. Tricalcium phosphate is used in powdered spices as an anti-caking agent. Calcium phosphate is an important raw material for the production of phosphoric acid and fertilizers, for example in the Odda process. Calcium phosphate is also a raising agent (food additives) E341. Is a mineral salt found in rocks and bones, it is used in cheese products. It is also used as a nutritional supplement. There is some debate about the different bioavailabilities of the different calcium salts. It is commonly used in porcelain and dental powders, and medically as an antacid or calcium supplement, although calcium carbonate is more common in this regard. Another practical application of the compound is its use in gene transfection. The calcium ions can make a cell competent (a euphemism for "rip holes in its membrane") to allow exogenous genes to enter the cell by diffusion. A heat shock afterwards then invokes the cell to repair itself. This is a quick and easy method for transfection, albeit a rather inefficient one.
