High performance gel chromatography (HPGC) was used to separate lipoproteins on the basis of their size and to generate lipoprotein profiles for plasma collected from patients with different lipoprotein phenotypes. These profiles provided a direct measurement of low density lipoprotein (LDL)-cholesterol which was more precise than LDL-cholesterol values calculated by the Friedewald equation. In addition, LDL-cholesterol concentrations were obtained in patients with combined hyperlipidemia in whom LDL-cholesterol could not be accurately calculated by the Friedewald equation. The response of LDL-cholesterol to the drug gemfibrozil was reliably monitored and in addition changes in LDL particle size could be assessed from the LDL apolipoprotein B/cholesterol ratio. HPGC also assisted in the diagnosis of type III hyperlipidemia by revealing a characteristic lipoprotein profile. HPGC-derived lipoprotein profiles provided additional useful clinical information for combined hyperlipidemia (Fredrickson lipoprotein phenotypes IIb, III).

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

D001055	Apolipoproteins B	Major structural proteins of triacylglycerol-rich LIPOPROTEINS. There are two forms, apolipoprotein B-100 and apolipoprotein B-48, both derived from a single gene. ApoB-100 expressed in the liver is found in low-density lipoproteins (LIPOPROTEINS, LDL; LIPOPROTEINS, VLDL). ApoB-48 expressed in the intestine is found in CHYLOMICRONS. They are important in the biosynthesis, transport, and metabolism of triacylglycerol-rich lipoproteins. Plasma Apo-B levels are high in atherosclerotic patients but non-detectable in ABETALIPOPROTEINEMIA.	Apo-B,Apo B,ApoB,Apoprotein (B),Apoproteins B
