Minyak ikan patin mengandung kadar asam lemak omega-9, tetapi rendah asam lemak omega 3 Minyak hati ikan hiu memiliki kandungan asam lemak omega 3 relatif tinggi. Penelitian ini bertujuan untuk menentukan karakteristik dan sifat kimia minyak ikan patin dan profil asam lemak kombinasi minyak ikan patin dengan hati kan hiu. Metode penelitian eksperimen dengan melakukan ekstraksi lemak perut ikan patin secara dry rendering dihasilkan minyak kasar dan dimurnikan. Minyak ikan patin murni dilakukan pencampuran dengan minyak hati ikan hiu. dengan perbandingan 1:1, 2:1 dan 2:1. Parameter analisis terdiri atas karakteristik kimia (bilangan asam lemak bebas (ALB),bilangan  asam, peroksida, iod,  p-anisidin, penyabunan, total oksida/totox), dan profil asam lemak. Hasil penelitian menunjukkan bahwa kombinasi  minyak patin dan hati ikan hiu dihasilkan karakteristik kimia terdiri atas asam lemak bebas sebesar 1,59-2,19%, bilangan asam 2,86-3,00 mg KOH/g, peroksida 15,50-18,32 meq/kg, iod 63,46-84,42 gI2/100g), p-anisidin 21,53-24,16, penyabunan 142,21-162,28 mg KOH/g dan TOTOX 53,33-69,43. Hasil analisis komposisi asam lemak jenuh (saturated fatty acid/SAFA) dihasilkan  asam palmitat tertinggi,  asam lemak tak jenuh tunggal  (mono unsaturated fatty acid/MUFA)  asam oleat,  dan asam lemak tak jenuh ganda (polyunsaturated fatty acid/PUFA)  asam linoleat. Hasil analisis karakteristik kimia kombinasi  minyak ikan patin dan hati ikan hiu sesuai dengan standar IFOMA. Kombinasi minyak hati ikan hiu dan ikan patin dengan perbandingan (2:1) dihasilkan kandungan omega 3 dan omega 6 sebesar 2,59 % dan 29,75%.

Various monohydroxylated fatty acids were synthesized from eicosapolyenoic acids, namely arachidonic (20:4 omega-6), timnodonic (20:5 omega-3), dihomogammalinolenic (20:3 omega-6) and mead (20:3 omega-9) acids. 12-Hydroxy derivatives, as well as 12-hydroxy-5,8,10-heptadecatrienoic acid (HHT), were produced with platelets as the enzyme source, and 15-hydroxy derivatives were produced by soya bean lipoxygenase treatment. Each monohydroxylated fatty acid was incubated with human leukocytes in the presence or absence of the calcium ionophore A23187, and dihydroxylated products were analysed by h.p.l.c. 12-Hydroxy derivatives of 20:4 omega-6, 20:5 omega-3 and 20:3 omega-9 were similarly oxygenated by both the 5-lipoxygenase and the omega-hydroxylase. As expected, the 12-hydroxy derivative of 20:3 omega-6 was not a substrate for 5-lipoxygenase, but surprisingly, omega-6 oxygenated products, like 15-OH-20:4 or HHT, were not converted by the enzyme, although being potential substrates because of the presence of two double bonds at C-5 and C-8. omega-6 oxygenated derivatives were also poorly converted by leukotriene B4 omega-hydroxylase, a cytochrome P-450-dependent enzyme. It is concluded that both leukocyte 5-lipoxygenase and omega-hydroxylase exhibit a substrate specificity towards monohydroxylated fatty acids with respect to their double bonds and/or the carbon position of the alcohol function.
