“…This opinion is based on the fact that phosphate may regulate the nucleotide metabolism [3] and stimulate glycolysis which may contribute to the elevated erythrocyte ATP production [4]. Furthermore, hypophosphatemia in both nonuremic [5] and uremic [6] patients is associated with reduced levels of erythrocyte ATP. These facts let us suppose that the serum phosphate concentration can be strongly correlated with the erythrocyte ATP concentration.…”
