| Abstract: | Analysis of phospholipids in porcine, bovine and rat adipose tissue revealed a relatively high level of plasmalogens (O-alk-1-enyl lipids). About 50% of the ethanolamine phospholipids in the pig and beef samples consisted of alk-1-enylacylglycerophosphorylethanolamine,
and the corresponding value for the rat sample was near 35%. In the ethanolamine and choline phospholipid fractions, theO-alk-1-enyl moieties were almost exclusively 16∶0, 18∶0 and 18∶1, whereas the acyl moieties had chain lengths ranging from
16 to 22 carbon atoms with a high degree of unsaturation. |
