Abstract
Summary
Atherosclerotic plaque, non-diseased aorta, liver and serum were collected from 5-8 year old White Carneau pigeons fed a grain diet. Lipids extracted from these tissues were fractionated into sterol esters, glyc-erides and phospholipids. Methyl esters of the component fatty acids of these fractions were prepared and quantified by gas-liquid chromatography. Unique fatty acid patterns of sterol esters were found in each of the various tissues. There is no difference in the fatty acid compositions of glycerides from the tissues studied. Phospholipids of plaques and non-diseased aorta exhibit similar fatty acid patterns as do those of liver and serum. However, the fatty acid compositions of phospholipids of plaque and non-diseased aorta are distinctly different from those of liver and serum. There is a remarkable resemblance between the fatty acid compositions of sterol esters and phospholipids of various tissues of pigeon and man.
