abstract：:The effects of palmitate on intracellular and extracellular amino acid concentrations of cultured astrocytes was studied. Exposure of astrocytes to either 0.72 mM or 0.36 mM palmitate was associated with a significant reduction in the intracellular pool of glutamine and taurine. In contrast, the intracellular concentr...
