[Intracellular and extracellular functions of phosphorus compound in the body].

Phosphorus, as a phosphate is a component of bone, cellular membrane, and also high-energy phosphate compounds, and nucleic acids. Also phosphate acts as a buffer to maintain the pH and is concerned with functional regulation of several proteins and intracellular signaling through the phosphorylation/dephosphorylation. Thus phosphorus plays a variety of important roles intracellular and extracellular component. A disorder of phosphate homeostasis results bone disorder and general metabolic dysfunction of all body tissues and organs.
