Polyunsaturated fatty acid enrichment from sardine oil by urea fractionationudand argentation chromatography

摘要

Fish and crustaceans cannot synthesize n3 andudn6 long chain polyunsaturated fatty acids (LCPUFAs)udde novo from precursor molecules. Of these,udeicosapentaenoic acid (EPA), docosahexanoic acidud(DHA), and arachidonic acid (AA) are essential in theuddiet of a majority of marine finfish and crustaceans,udespecially for the larvae and broodstock. PUFAs areudwidely available in a large variety of marine organismsudlike microalgae, polychaetes, finfish and shellfish, butudfish oil is easily available, cheap, and containudconsiderable amount of PUFAs.
