Crayfish ventral nerve cord and hemolymph: content of free amino acids and other metabolites

, : Crayfish ventral nerve cord and hemolymph: content of free amino acids and other metabolites. Comparative Biochemistry and Physiology. B, Comparative Biochemistry 45(1): 249-263

1.1. Non-protein amino acids and related compounds in the ventral nerve cord (VNC) and the hemolymph of the fresh-water crayfish Orconectes immunis have been determined by ion-exchange chromatography. Some other metabolites have also been measured.2.2. A total of twenty-six and twenty-seven amino compounds has been found in the VNC and the hemolymph, respectively.3.3. The VNC contained over ten times as much total amino compounds as the hemolymph.4.4. Some pharmacologically active amino acids such as GABA, glutamate and aspartate existed in even higher content in the VNC than in the hemolymph.5.5. The significance of such disparity in distribution has been discussed.
