a comparison was made of acute and chronic effects of ammonia on production of 14co2 from the [ u-14c ] labeled branched-chain amino acids ( bcaa ) leucine , isoleucine , and valine as well as from [ 1-14c ] leucine , and on the incorporation of radioactivity from these amino acids into a perchloric-acid-precipitable protein fraction in astrocytes and neurons in primary cultures .
