Phosphate requirements

Physiology:

Phosphate is a major intracellular anion important for intracellular metabolism of proteins, fats and carbohydrates and is a major component in phospholipid membranes and phosphoproteins.  It also regulates enzymatic activity vital for energy transfer.  About 4 mEq/g of nitrogen is needed for anabolism.  85% of total body phosphates are combined with calcium in the bones and teeth.  Factors affecting calcium homeostasis also affect phosphate homeostasis, movement is the opposite of calcium.

Empiric daily requirement

Adults: 10 to 40 mMol/day

Infants/children: 0.5 to 2 mMol/kg/day
