Nutritional interrelationships of electrolytes and amino acids.
Evidence for interactions between amino acid and electrolyte metabolism is reviewed. Variations in dietary sodium, potassium, and chloride concentrations affect acid-base balance and also influence the severity of the lysine-arginine antagonism. High dietary levels of Na and K salts of metabolizable organic acids alleviate, whereas excessive dietary chloride exacerbates, the antagonism. Potassium deficiency causes depletion of intracellular potassium and increased intracellular accumulation of basic amino acids. These variations in electrolytes, which alter acid-base balance, also influence the metabolism of glutamic acid and the excretion of nitrogen. It is hypothesized that basic amino acids as well as glutamic acid and glutamine may have an important role in metabolic regulation of acid-base balance.
