Abstract
The analysis, by silica-gel chromatography, of phospholipids from a human-plasma fraction is described. The fraction was derived from whole blood which had been incubated with sodium [Me-14C]acetate for 6.5 hr. The 0-lipoproteins had been removed by precipitation with dextran sulfate. All the phospholipids isolated were labeled. The fatty acids of the isolated phospholipids were analyzed by vapor-phase chromatography. A comparison of yield, radioactivity and fatty acid distribution with those for the phospholipids of the cells is given.
