phosphate

 [fos´fāt]
any salt or ester of phosphoric acid. adj., adj phosphat´ic.

Phosphates are widely distributed in the body, the largest amounts being in the bones and teeth. They are continually excreted in the urine and feces and must be replaced in the diet. Inorganic phosphates function as buffer salts to maintain the acid-base balance in blood, saliva, urine, and other body fluids. The principal phosphates in this buffer system are monosodium and disodium phosphate. Organic phosphates, in particular adenosine triphosphate (ATP), take part in a series of reversible reactions involving phosphoric acid, lactic acid, glycogen, and other substances, which furnish the energy expended in muscle contraction. This is thought to occur through the hydrolysis of the so-called high-energy phosphate bond present in ATP, phosphocreatine, and certain other body compounds.
