in addition to analyzing fasting plasma lipids ( cholesterol and triglyceride ) , we used two chemical techniques to measure the three major classes of lipoproteins : ultracentrifugation with heparin/manganese precipitation which yielded values for hdl- , ldl- and vldl-cholesterol , and quantitative electrophoresis which yielded values for alpha- , beta- and pre-beta-lipoprotein .
