Interaction of human low-density lipoproteins (LDL) with discoidal complexes comprised of egg yolk phosphatidylcholine and human apolipoprotein A-I (molar ratio, 88:1, respectively) was investigated. The multicomponent gradient gel electrophoretic pattern of LDL is transformed to one that includes a predominant component with an apparent particle diameter larger than that of the initial major LDL but still in the size range of normal LDL. The apparent particle diameter increase (range, 0.2-3.5 nm) is proportional to the increase (range, 6-40%) in LDL phospholipid/protein weight ratio following incubation (37 degrees C; 6 and 24 h); the smaller the initial LDL diameter, the greater the apparent particle diameter increase and percentage of phospholipid uptake. The LDL unesterified cholesterol/protein weight ratio decreases (range, 33-39%), but does not correlate with the increase in apparent particle diameter value. Interaction products are round particles with intact apolipoprotein B and show no evidence of phospholipid degradation. The products appear more dense than expected from the size vs. density relationship observed for nonincubated LDL subspecies. In addition to products in the normal LDL size range, larger components (apparent particle diameter range, 29.0-41.2 nm) also form and may be association complexes of phospholipid-modified LDL. Our results indicate that phospholipid uptake by LDL may contribute to the particle size polydispersity observed in plasma LDL.
