The lipoproteins are the proteins that enable cholesterol to move through the blood. High density lipoproteins (HDL) are called good cholesterol, because the HDLs stransport the cholesterol out of the body. Low density lipoproteins are called bad cholesterol, because they clog the arteries. During a lipoprotein profile, the doctor will also measure triglycerides, which store most of the body's fat.
