Marine organisms have been increasingly regarded as good sources of new drugs for human therapeutics and also as nutrients for human diet. The amino acids, fatty acids and sterols profile of the widely consumed echinoderms Paracentrotus lividus Lamarck (sea urchin) and Holothuria forskali Chiaje (sea cucumber) and of the gastropod molluscs Aplysia fasciata Poiret and Aplysia punctata Cuvier (sea hares) from the Portuguese waters were established by GC-MS analysis. Overall, 10 amino acids, 14 fatty acids and 4 sterols were determined. In a general way, all species presented the ten amino acids identified, with the exceptions of H. forskali, in which no glycine, proline, trans 4-hydroxy-proline and phenylalanine were found, and of A. fasciata that did not contain proline. Unsaturated fatty acids were predominant compounds, those from the ω-6 series being in higher amounts than their ω-3 homologues, and cholesterol was the main sterol. The amino acids, fatty acids and sterols composition of A. fasciata, A. punctata and H. forskali is reported here for the first time.
