Lipoprotein

Definition: A lipoprotein consists of a protein that is combined to a lipid, or fat. Lipids typically do not travel alone in the blood. Instead, they bind to a protein that will carry it to its correct destination in the body.

There are many different types of lipoproteins circulating in the body, including:

• Very low density lipoproteins (VLDL)
• Intermediate density lipoproteins (IDL)
• Low density lipoproteins (LDL)
• High density lipoproteins (HDL)

Each of these particles perform different functions and can be detrimental (VLDL, IDL, LDL) or beneficial (HDL) to your heart health.
