Title

Trace elements in wild edible Aplysia species: relationship with the desaturation–elongation indexes of fatty acids

Abstract

The profile of essential and non-essential elements was traced in the edible sea hares Aplysia depilans Gmelin, Aplysia fasciata Poiret and Aplysia punctate Cuvier. Manganese (Mn), iron (Fe), zinc (Zn), copper (Cu) and selenium (Se) were identified as the major essential elements. Risk assessment evidenced that the levels of cadmium (Cd) and lead (Pb) did not exceed the maximum limit value established by the European Regulation, the contents of chromium (Cr), nickel (Ni) and arsenic (As) being also below the levels established by the FDA guide. A correlation between trace elements levels and desaturation–elongation indexes of fatty acids was found. While Cd, Se and molybdenum (Mo) seem to promote the desaturation–elongation process involved on the production of C20:4n-6c, Ni, Cr and Fe may potentiate the conversion of C18:3n-3c to C20:5n-3c. Furthermore, cobalt (Co), Ni and Cu appear to decrease Δ9 desaturation index. Besides the suggested biosynthetic switch modulated by trace elements, the nutritional value of the species is further strengthened.
