[Various changes in the composition of blood serum phospholipids and lipoproteins in arteriosclerosis]. 1976

T I Torkhovskaia, and N M Lobova, and E N Levitova

The composition of phospholipids of plasma lipoproteins was studied in normal individuals and in patients with coronary atherosclerosis with type IIb and IV hyperlipoproteidemia using two-dimentional thin-layer chromatography. It was demonstrated that in normals the fractions of lipoproteins of a very low, low and high density have an even distribution of most of the phospholipid components, lecithin and sphyngomyelin being the prevailing phospholipids in all fractions of lipoproteins. In type IIb and IV hyperlipoproteidemia, lipoprotein fractions of very low density have a relatively elevated content of lecithin and those of high density have an elevated content of lecithin and lysolecithin and a decreased level of sphyngomyelin. The obtained data are discussed in terms of the possible effect of the chemical composition of phospholipids on the properties of lipoproteins in atherosclerosis.

UI MeSH Term Description Entries
D008074 Lipoproteins Lipid-protein complexes involved in the transportation and metabolism of lipids in the body. They are spherical particles consisting of a hydrophobic core of TRIGLYCERIDES and CHOLESTEROL ESTERS surrounded by a layer of hydrophilic free CHOLESTEROL; PHOSPHOLIPIDS; and APOLIPOPROTEINS. Lipoproteins are classified by their varying buoyant density and sizes. Circulating Lipoproteins,Lipoprotein,Lipoproteins, Circulating
D010712 Phosphatidic Acids Fatty acid derivatives of glycerophosphates. They are composed of glycerol bound in ester linkage with 1 mole of phosphoric acid at the terminal 3-hydroxyl group and with 2 moles of fatty acids at the other two hydroxyl groups. Ammonium Phosphatidate,Diacylglycerophosphates,Phosphatidic Acid,Acid, Phosphatidic,Acids, Phosphatidic,Phosphatidate, Ammonium
D010743 Phospholipids Lipids containing one or more phosphate groups, particularly those derived from either glycerol (phosphoglycerides see GLYCEROPHOSPHOLIPIDS) or sphingosine (SPHINGOLIPIDS). They are polar lipids that are of great importance for the structure and function of cell membranes and are the most abundant of membrane lipids, although not stored in large amounts in the system. Phosphatides,Phospholipid
D006801 Humans Members of the species Homo sapiens. Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D001161 Arteriosclerosis Thickening and loss of elasticity of the walls of ARTERIES of all sizes. There are many forms classified by the types of lesions and arteries involved, such as ATHEROSCLEROSIS with fatty lesions in the ARTERIAL INTIMA of medium and large muscular arteries. Arterioscleroses
D013109 Sphingomyelins A class of sphingolipids found largely in the brain and other nervous tissue. They contain phosphocholine or phosphoethanolamine as their polar head group so therefore are the only sphingolipids classified as PHOSPHOLIPIDS. Sphingomyelin
