    Research output: Contribution to journalArticlepeer-review


    The plasmalogen content and composition in the low density lipoprotein (LDL) and high density lipoprotein (HDL) of the fish were analyzed. The composition of the plasmalogen in the carp plasma LDL phospholipids was 0.94% and 0.23% in the HDL; the LDL phospholipids in the rainbow trout were 0.44% and the HDL was 0.18%. Aldehydes from the plasmalogen were derivatized with dansylhydrazides and separated by high performance liquid chromatography (HPLC), their presence was detected using a fluorescence detector. Hexadecanal (C16: 0), octadecanal (C18: 0) and octadecenal (C18: 1) were determined to be the major components in the carp and rainbow trout. The plasmalogen content in the plasma lipoprotein phospholipid was much lower than that in the brain, heart and ordinary muscle. Although the alkyl dihydroxyacetone phosphate (DHAP) synthetic ability was recognized in these tissues, the alkyl DHAP was also synthesized in the liver. It was indicated that lipoprotein included in plasmalogen was synthesized in the liver.
