A potassium ion, one of the main electrolytes in the cell,
has actions such as to induce the membrane potential, to maintain the osmotic
pressure and to control the acid-base equilibrium.
When the red blood cell is employed as a sample to examine
the transport of potassium into the tissues, potassium L-aspartate proves a
beter intake by the tissues than potassium chloride.
ABSORPTION AND EXCRETION :
When the amount of Potassium L-aspartate equivalent to 20
mEq/kg/day of potassium was administered for 32 days to rats fed on food
lacking porassium for 24 days, the eman amount of potassium excreted in the
feces was 26.1 µEq/head/day.
Namely, the absorption rate of potassium from the intestines was not less than
99,5% because the mean administration amount of potassium was 5,497 µEq/head/day.
