percentage of lipid in the lipoprotein) due to water insolubility
IDL - Answer-is more likely to cause atherosclerosis than a similar amount of LDL
cholesterol
serum cholesterol - Answer-is a composite of the total cholesterol contained in each of
the different lipoproteins
cholesterol distribution - Answer-among the various lipoproteins is a more powerful
predictor of heart disease than total blood cholesterol
