Isolation and characterization of apolipoprotein B-48 and B-100 very low density lipoproteins from type III hyperlipoproteinemic subjects.
Two major species of human apolipoprotein (apo) B have been identified, apo B-48 and apo B-100, which are the predominant forms in chylomicrons and very low density lipoproteins (VLDL), respectively. Due to defective hepatic clearance, apo B-48 containing lipoproteins accumulate in the plasma of subjects with type III hyperlipoproteinemia. In the present study, we have used immunoaffinity chrom...
متن کاملApolipoprotein B-48 and B-100 very low density lipoproteins. Comparison in dysbetalipoproteinemia (type III) and familial hypertriglyceridemia (type IV).
A protein band having the same migration as apolipoprotein (apo) B-48 was observed by SDS electrophoresis in the plasma very low density lipoprotein (VLDL) from 14 Type IV and three Type III hyperlipoproteinemic subjects and from six normal fasting subjects. The VLDL from five Type IV, three Type III, and one normal subject were separated into two subfractions, retained and nonretained, by immu...
متن کاملStructural organization of apolipoprotein B-100 of human plasma low density lipoproteins. Comparison to B-48 of chylomicrons and very low density lipoproteins.
The present study characterizes the substructural organization of apolipoprotein B-100 (B-100) of human plasma low density lipoproteins (LDL) and its relation to B-74 and B-26 of LDL and B-48 of chylomicrons and very low density lipoproteins. LDL were digested with human kallikrein and thrombin to yield two major fragments: K1 (Mr 410,000) and K2 (Mr 145,000) and T1 (Mr 385,000) and T2 (Mr 170,...
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 کاملApolipoprotein 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...
