title: Proteins, fatty acids and nutritional value in the muscle of the fish species Mora moro (Risso, 1810).
abstract: Deep-water fish are becoming an interesting object of studies and research due to the development of deep fishery activities. This paper analyses the chemical composition and nutritional value of the fish species Mora moro (Risso, 1810) inhabiting deep Mediterranean waters. The fatty acid profile and the principal water-soluble proteins present in the white muscle of this fish species have also been determined. The major fatty acids were 22 : 6n-3, 16 : 0, 18 : 1n-9, 20 : 4n-6 and 20 : 5n-3. The polyunsaturated fatty acid (PUFA) content was higher than that of saturated (SFA) and monounsaturated fatty acids, but the ratio PUFA/SFA was lower than the value reported in other studies. Both the atherogenic index and thrombogenic index were very low. Water-soluble proteins were characterised by monodimensional native PAGE and 2-D SDS-gel electrophoresis. Protein patterns showed the presence of parvalbumins and of the principal myofibrillar proteins. Therefore, the deep-water fish M. moro could represent an interesting target for deep-sea fishery and commercial exploitation.
