BACKGROUND

Lipids are compounds, including fatty acids, cholesterol, and triglycerides, that play important roles in energy storage, body insulation, cell structure and function, steroid hormone synthesis, and metabolic regulation. Because lipids are not soluble in body fluids, they must combine with apolipoproteins (apo) to form lipoproteins for transport throughout the body. When joined with apolipoproteins, these newly formed lipoproteins take on a spherical shape that surrounds a lipid core containing triglycerides, phospholipids, free cholesterol, and esterified cholesterol. Lipoproteins are categorized by ultracentrifugation according to their gravitational density (53), with as many as 17 different apolipoproteins associated with the
