Comparative study on the fatty acid composition of two marine vertebrates: striped dolphins and loggerhead turtles.

摘要: Abstract The fatty acid composition of total lipids extracted from seven different tissues (fat, liver, cerebrum, cerebellum, lung, kidney and muscle) 10 striped dolphins ( Stenella coeruleoalba ) (weight 75.7±16.2 kg) found dead or moribund during a morbillivirus epizootic, two (fat liver) 54 loggerhead turtles Caretta caretta (18.5±10.5 seized after illegal capture, both the Mediterranean Sea, have been determined by high resolution chromatography techniques. When comparing species, is surprisingly similar, with predominance monoenoic followed saturated group acids, very close ratio polyunsaturates n-3/n-6. relatively arachidonic content in liver marine species remarkable. similar diet can play an important role these findings, but it suggested that probably metabolic pathways essential requirements between vertebrates are more than expected their earlier filogenetic evolutionary divergence.
