Some properties of very low density lipoproteins were studied under conditions causing an increase of their concentration in blood plasma. Content of high molecular apolipoprotein B and low molecular lipoproteins were estimated after fractionation using column chromatography and selective precipitation with tetramethylurea. In 216 men (40-59 years old) with hypertriglyceridemia the increase in content of particles of very low density lipoproteins was accompanied by simultaneous alteration in their composition in blood plasma: content of low molecular polypeptides, triglycerides and cholesterol was increased per a weight unit of apoprotein B. At the same time, the absolute concent of apoprotein B and of low molecular apoproteins of very low density lipoproteins was increased in blood plasma. The most distinct alteration in the ratio of apolipoproteins to very low density lipoproteins was observed, if content of testosterone--activator of lipoprotein lipase--was decreased in blood plasma.

UI MeSH Term Description Entries
D006949 Hyperlipidemias Conditions with excess LIPIDS in the blood. Hyperlipemia,Hyperlipidemia,Lipemia,Lipidemia,Hyperlipemias,Lipemias,Lipidemias
D008079 Lipoproteins, VLDL A class of lipoproteins of very light (0.93-1.006 g/ml) large size (30-80 nm) particles with a core composed mainly of TRIGLYCERIDES and a surface monolayer of PHOSPHOLIPIDS and CHOLESTEROL into which are imbedded the apolipoproteins B, E, and C. VLDL facilitates the transport of endogenously made triglycerides to extrahepatic tissues. As triglycerides and Apo C are removed, VLDL is converted to INTERMEDIATE-DENSITY LIPOPROTEINS, then to LOW-DENSITY LIPOPROTEINS from which cholesterol is delivered to the extrahepatic tissues.
