Metabolismo y requerimiento de ácidos grasos esenciales en el pulpo común (Octopus vulgaris)

Abstract

[ES] La presente comunicación es una recopilación de diversos estudios sobre el metabolismo de los ácidos grasos poliinsaturados en pulpo común (Octopus vulgaris), a través de ensayos in vivo e in vitro llevados a cabo en los últimos años en el marco de varios proyectos. Estos estudios sugieren que los ácidos grasos araquidónico (ARA), eicosapentaenóico (EPA) y docosahexaenóico (DHA) han de ser considerados esenciales en el desarrollo de esta especie y que el uso de Artemia en la alimentación de la paralarva da lugar a una deficiente incorporación de DHA en este cefalópodo. Finalmente, también se han identificado en esta especie enzimas ω3 desaturasas, no descritas en vertebrados, y que son capaces de sintetizar ácidos grasos de la serie n-3 a partir de sus precursores de la serie n-6.

[EN] The present communication is a review on the metabolism of polyunsaturated fatty acids in common octopus (Octopus vulgaris), through in vivo and in vitro studies carried out in the last few years within the frame of several projects. These studies suggest that arachidonic (ARA), eicosapentaenoic (EPA) and docosahexaenoic (DHA) fatty acids (FA) must be considered as essential for octopus development and that DHA supplied through Artemia display a very poor incorporation into the paralarvae lipids. Finally, ω3 desaturase enzymes which synthesize n-3 FA from their corresponding n-6 series precursors, have been also identified in this species.

Estos estudios han sido subvencionados por los proyectos OCTOPHYS (AGL2010-22120-CO3) y OCTOWELF (AGL2013-49101-C2-1-R). El trabajo de D.B. Reis y A.V. Sykes fue subvencionado a través de los programas FCT (SFRH/BD/76863/2011 y IF/00576/2014, Portugal) y el de D. Garrido con una beca del IEO (3rd Nov. 2011). C. Rodríguez es miembro del ITB de canarias.
