Setaria cervi: lipid biosynthesis from C14-labelled acetate and glucose in the two sexes and microfilariae.

Microfilariae (mf), males and females of Setaria cervi were able to synthesize several important classes of lipids and thus exhibited a functional lipid metabolism. The incorporation of the C14 label from acetate into lipids was relatively greater than that from glucose in adults, whereas label from glucose was incorporated to a greater extent in mf. Though only a small portion of these precursors, was utilized for the non-polar (NP) lipid synthesis, they were the preferred substrate for the polar lipid (P) synthesis; the P/NP ratios being 5.2 (mf), 1.63 (male) and 5.16 (female) for acetate and 1.23 (mf), 1.06 (male) and 2.25 (female) for glucose.
