[Comparative characteristics of the fatty acid composition of lipoproteins in human blood plasma and aortic wall].

A study was made of a fatty acid composition of individual lipid fractions in the lipoproteids of the blood serum of a very low, low and high density, and the wall of the aorta affected with atherosclerosis. There was a close similarity between a fatty acid composition of phospholipids, triglycerides, and cholesterol esters of all the lipoproteid classes of the vascular wall and blood plasma. The fatty acid compostion of individual fractions proved to be similar in all the lipoproteid fractions. The lipids of the vascular wall not included into the lipoproteid composition differed considerably by their fatty acid composition from the lipids isolated from lipoproteids; lipids of the wall of the aorta contained much less unsaturated fatty acids than lipoproteids.
