The fact that in animals the concentration of glutamate and glutamine are higher in brain than in any other tissue initially attracted interest in attempting to understand the function or functions of these amino acids in the central nervous system. They were evidently required for protein synthesis and early studies established their close relationship to the Krebs tricarboxylic acid cycle and energy metabolism in brain. Glutamine formation in brain was also shown to be sensitive to elevations in plasma ammonia levels and to serve as the primary method for detoxifying this substance in brain in contrast to urea formation in ...

Crystals were prepared by reacting the K salt of ureidotaurine with ninhydrin in acid solution. The product shows that the unsubstituted N -of the ureidotaurine reacts with the central C of ninhydrin
