Abstract

Here we present free amino acid profiles for Drosophila melanogaster adults. Imidazol dipeptides anserine and carnosine, which are abundant in mammalian muscle tissue, are not present in Drosophila. Dipeptide-enriched food altered the amino acid balance, suggesting that the free amino acid content is nutrition-dependent and probably mediated by dipeptides.
