Amino Acid Analyzer

AbstractExtracts of free amino acids from six species of ants (Pogonomyrmex barbatus (F. Smith), P. occidentalis (Cresson), Tapinoma sessile (Say), Camponotus pennsylvanicus (DeGeer), Conomyrma pyramica (Roger), and Novomessor cockerelli (E. André) were analyzed by thin layer, one and two dimensional paper chromatography, and an automatic amino acid analyzer to determine the potential use of qualitative and (or) quantitative data of the free amino acid composition of ants in taxonomic studies. The results demonstrate that no significant qualitative differences exist, but that the automatic amino acid analyzer may be used to show significant quantitative differences in the free amino acid composition of the ants studied.

The Brain

1.The effects of protein-energy malnutrition on brain free amino acids of acidic and neutral groups were investigated in experimental rats.2.Severe energy restriction did not modify the free amino acid composition of the brain while protein deficiency affected certain amino acids of the brain in opposite directions. Significant decreases in the levels of aspartic acid, threonine and tyrosine were observed in the protein-deficient rats.3.These changes in brain amino acids appear to be specific to protein deficiency and not affected by energy deficiency.
