Docosahexaenoic acid DHA, the end-product of the metabolism of omega-3 family fatty acids, is the main polyunsaturated fatty acid of the brain, but its accumulation is incompletely understood. This paper reviews how it could accumulate through specific uptake of DHA-containing lysophosphatidylcholine LysoPC-DHA. DHA migrates very easily from the sn-2 position of LysoPC, which could be considered as the physiological form of polyunsaturated LysoPC, to the sn-1 position, which is much more stable. An approach preventing migration by acetylating the sn-1 position, while retaining the main physico-chemical properties of the carrier, is described. Also, the double lipoxygenation and bond-isomerization of DHA into 10S,17S-docosahexa-4Z,7Z,11E,13Z,15E,19Z-enoic acid, named PDX, by soybean lipoxygenase is described. As in other E,Z,E conjugated trienes, PDX is shown to inhibit human blood platelet aggregation at submicromolar concentrations.
