Phosphate plays a critical part in the regulation of cell metabolism,and phosphate homeostasis is closely regulated in normal humans.Indeed, like serum calcium, serum phosphate is maintained withina narrow range of values, and people with abnormal concentrationsmay have a predisposition to life-threatening conditions, suchas hemolysis, myopathy, hypocalcemia, and nephrocalcinosis.
The principal organ that regulates phosphate homeostasis isthe kidney. Regulation is accomplished partly through variationin glomerular filtration of phosphate but primarily throughvariation in renal tubular reabsorption of phosphate. Thesevariations are detectable within 24 hours after a change indietary phosphate intake and even . . . [Full Text of this Article]
