derivatives thereof, particularly phosphatidylserine (PS),
phosphatidylcholine (PC), phosphatidylethanolamine (PE),
phosphatidyl-inositol (PI), phosphatidylglycerol (PG) and phosphatidic
acid (PA), and poly-unsaturated fatty acid (PUFA) acyl groups,
particularly long-chain poly-unsaturated fatty acid (LC-PUFA) acyl groups
such as omega-3 and/or omega-6 acyl groups, wherein said PUFA is
covalently bound to said glycerophospholipid. The preparation possesses
