Abstract

Jedni od najpoznatijih spojeva organske kemije, koji sudjeluju u raznovrsnoj regulaciji mehanizama stanice, a time i cijelog organizma, jesu masne kiseline. One imaju bitnu ulogu na više područja. Služe kao signalne molekule, sudjeluju u izgradnji membrana i predstavljaju izvor energije i pogonsko gorivo za organizam. Zbog svoje svestranosti razlikujemo više podjela masnih kiselina pa govorimo o podjeli na razni zasićenosti i nezasićenosti (količini dvostrukih veza), broju ugljikovih atoma, esencijalnosti i neesencijalnosti, na razini vezanosti za druge biokemijske molekule (slobodne ili vezane masne kiseline), itd. Masne kiseline pronalazimo i kod riba, gdje sudjeluju u sazrijevanju gonada, toplinskoj prilagodbi, imunološkom sustavu i pohrani energije. Ribe koje su važne zbog svoje mogućnosti proizvodnje esencijalnih masnih kiselina dolaze iz porodice jeguljki. Predstavnici su im jegulja i murina. Cilj istraživanja ovoga rada je usporediti sastav masnih kiselina ovih dviju vrsta.

Abstract (english)

Some of the best known compounds of organic chemistry that participate in the regulation of diverse regulation mechanisms of cells, and consequently the whole body, are the fatty acids. Thus, they have important role in several areas. They serve as signaling molecules, participate in the construction of membranes and they are a source of energy and fuel for the organism. Due to its versatility we can find different divisions of fatty acids. For example, division based on different saturation and unsaturation (amount of double bond), the number of carbon atoms, essentiality and non-essentiality, and the level of attachment to other biochemical molecules (free or bound fatty acids), etc. We can find fatty acids in fish, where they participate in the maturation of the gonads, thermal adaptation, immune system and saving energy. Because of their possibilities of production of the essential fatty acids, members of the order Anguilliformes (True eels), are of high importance. Their representatives are European eel and Mediterranean moray. The aim of this work is to compare the fatty acid composition of these two species.
