Fatty acid composition of the cholesteryl esters extracted from RAW Cells and, for purposes of comparison, the fatty acid composition of Nat-LDL.

Quantitative lipidomic analysis of the intracellular cholesteryl esters in lipid extracts of cells incubated for 24 or 48 h with 300 µg/ml of Ac- or Chs-LDL. Only the major cholesteryl esters are represented in the table. Changes in the content of Cholesteryl oleate (18∶1) and Cholesteryl Linoleate (18∶2) are highlighted. Lipid extracts of native LDL were used as control. The cholesteryl esters distribution is shown as percentage of total cholesteryl esters. The results are the mean ± SD of three independent experiments obtained with three different LDL preparations.
