What is The desaturation and elongation of 14C-labelled polyunsaturated fatty acids by pike (Esox lucius L.) in vivo about?

To examine the ability of pike (Esox lucius L.) to modify exogenous PUFA by desaturation and elongation, (14)C-labelled 18:2(n-6), 18:3(n-3), 20:4(n-6) and 20:5(n-3) were injected intraperitoneally and the distribution of radioactivity in tissue lipid classes and liver PUFA measured. In all tissues examined, radioactivity from all (14)C-PUFA was recovered in many classes of acyl lipids and the level of recovery generally reflected the relative abundance of the lipid classes. Triacylglycerols, CGP and EGP usually contained high levels of all incorporated (14)C-PUFA. PI contained higher levels of radioactivity from (14)C-20:4(n-6) than from other injected substrates. In liver lipid, the Δ6 desaturation products of (14)C-18:2(n-6) and (14)C-18:3(n-3) contained no measurable radioactivity although the elongation products of the Δ6 desaturation products were labelled, as were the direct elongation products of these injected substrates. No radioactivity from (14)C-18:2(n-6) or (14)C-18:3(n-3) was detected in C20 or C22 products of Δ5 and Δ4 desaturation. Almost all radioactivity from injected (14)C-20:4(n-6) was recovered in this PUFA. Of the total radioactivity from (14)C-20:5(n-3) inco
