Potassium
The concentration of potassium in the body is 2 g/kg.
At a concentration of 140 mmol/L, it is the most common cation in the intracellular fluid.
Potassium is localized mostly within the cells.
It regulates the osmotic pressure within the cells, is involved in cell membrane transport and also in the activation of a number of glycolytic and respiratory enzymes.
The potassium intake in a normal diet is 2 – 5.9 g/day. The minimum daily requirement is estimated to be 782 mg.
Potassium deficiency is associated with a number of symptoms and may be a result of undernourishment or predominant consumption of potassium-deficient foods, e.g., white bread, fat or oil.
