Phosphatidylcholine (PC), the main phospholipid in eukaryotes, is synthesized via two different routes, the phosphatidylethanolamine N-methyl transferase (PEMT) and the CDP-choline pathways. We previously showed in euryhaline fish that salinity impac

Total fatty acid (FA) fluxes of teleost have been well characterized, but the tissues incorporating FA from the circulation and the metabolic fate of these FA remain unclear. Our goals were to determine (i) the relative roles of different tissues in

The turnover rates of palmitate and oleate were measured in vivo by continuous infusion of 1-[14C]palmitate and 9,10-[3H]oleate in rainbow trout. Our goals were: (1) to quantify the incorporation of a saturated and of a monounsaturated fatty acid int

The effects of l -thyroxine on phospholipid biosynthesis, via 32 P incorporation, were studied in gill, kidney, liver and muscle tissue of eels acclimatized at 11°C. l -thyroxine treatment had no effect on tissue content of lipid, inorganic and orga

Second messenger ceramides differ in their composition according to the nature of their sphingoid bases and their amide linked fatty acids. These different species may be involved in many different biological responses, as may be the diacylglycerol s

We have studied the incorporation of radioactivity from either [3-3H]serine as the direct or [3H-methyl]methionine as the indirect precursor into sphingoid bases of free ceramides in lymphocytes from fish. Radioactivity from serine was incorporated m

Contribution of base-exchange of serine with other phospholipids for the synthesis of phosphatidylserine (PS), followed by PS decarboxylation to phosphatidylethanolamine (PE) and N -methylation of PE was studied, in vivo and in vitro, in euryhaline f

In this report we demonstrate the presence of a phospholipid N-methylation in tissues of fish and crustaceans. In liver and hepatopancreas this pathway participates very actively to the synthesis of different molecular species of PC which are later e

We have developed a novel, simple, and rapid, two-dimensional thin-layer chromatography method to separate 1,2-, 1,3-diacylglycerols and ceramides containing alpha-hydroxy and normal fatty acids from other neutral lipids on one 10 x 10 cm precoated s

Temperature shift from 12 to 22°C induced significant changes in the gill phospholipids of the crab Carcinus maenas 24 hr after temperature change. High temperature adaptation affects the distribution of l -3( 3 H)serine in phosphatidylcholine (PC),
