Figure 1From: Functional genomics reveals increases in cholesterol biosynthetic genes and highly unsaturated fatty acid biosynthesis after dietary substitution of fish oil with vegetable oils in Atlantic salmon (Salmo salar)Expression of various enzyme activities in vegetable oil fed Atlantic salmon. Results are expressed relative to fish oil. Those which are significantly different from fish oil (p ≤ 0.05 t-test) are indicated with an asterisk. BOX, total palmitoyl CoA beta-oxidation; CPT1, carnitine palmitoyl CoA transferase; HUFA, highly unsaturated fatty acid synthesis; ME, malic enzyme. Specific enzyme activities for control fish are: BOX, 33.6 ± 4.7 pmol palmitoyl-CoA oxidised/min/mg protein; CPT1, 56.7 ± 14.8 pmol palmitoyl-carnitine produced/min/mg protein; HUFA, 2.88 ± 0.1 pmol linolenic acid desaturation products/h/mg protein; ME, 69.8 ± 15.2 nmol malate oxidised/min/mg protein.Back to article page
