Apolipoprotein B 100 and 48
Apolipoprotein B is the main structural surface protein found on all beta-lipoproteins (Chylomicrons, VLDLs, IDLs and LDLs). There is a single molecule of apoB on each of those lipoproteins. It is the only apolipoprotein that is not transferablei.e. it is with the particle from its birth till its death. Beta-lipoproteins are the lipoproteins capable of trafficking cholesterol into the artery wa...
متن کاملStructure of apolipoprotein B-100 of human low density lipoproteins.
We have analyzed low density lipoproteins (LDL) apolipoprotein (apop) B structure by direct sequence analysis of LDL apo B-100 tryptic peptides. Native LDL were digested with trypsin, and the products were fractionated on a Sephadex G-50 column. The partially digested apo B-100 still associated with lipids was recovered in the void volume (designated trypsin-nonreleasable, TN, peptides). The re...
متن کاملThe association between small dense low density lipoprotein,apolipoprotein B, apolipoprotein B/apolipoprotein A1 ratio and coronary artery stenosis
Abstract Background: Recently, small dense low density lipoprotein (sdLDL) has been highlighted as a new risk factor for the coronary artery disease (CAD).Small dense LDLs are believed to be atherogenic since these particles are taken up more easily by arterial wall. They are readily oxidized and have reduced affinity for low density lipoprotein (LDL) receptor and increased affinity...
متن کاملEstimation of LDL-associated apolipoprotein B from measurements of triglycerides and total apolipoprotein B.
BACKGROUND VLDL and chylomicrons may interfere with measurements of apolipoprotein B (apo B) on LDL particles. Ultracentrifugation of samples enriched in chylomicrons and VLDL and subsequent measurement of apo B in the infranate fraction [density (d) = 1.006] removes this interference. This apo B fraction is called "LDL-apo B." METHODS We retrospectively analyzed 64 895 measurements of trigly...
متن کاملFlow cytometric assessment of LDL ligand function for detection of heterozygous familial defective apolipoprotein B-100.
BACKGROUND Familial defective apolipoprotein (apo) B-100 (FDB) is caused by a mutation in the apoB gene and characterized by decreased binding of LDL to LDL receptors because of reduced function of the apoB-100 ligand. FDB may be associated with severe hypercholesterolemia and cannot always be distinguished from familial hypercholesterolemia phenotypically. METHODS We used a fluorescence flow...
