STUDIO COMPARATIVO DEL CONTENUTO LIPIDICO E DEL PROFILO DEGLI ACIDI GRASSI DI HOLOTHURIA TUBULOSA E H. POLII

Total lipids and fatty acids of four tissues (external and internal body wall, longitudinal muscle and gonad) of Holothuria tubulosa (Gmelin, 1788) and H. polii Delle Chiaje, 1824, from Ionian Sea, were evaluated. Highest lipids % were found in H. polii in the most part of tissues, except for external body wall. H. tubulosa was characterized by highest proportion of polyunsaturated fatty acids, except for gonad, while, H. polii showed an uniform distribution of fatty acids class in the investigated tissues.
