Lipoproteins

High-density lipoprotein (HDL) removes cholesterol from tissues in the body and transports it to cells that need cholesterol and to the liver for removal. Low-density lipoprotein (LDL) formed from VLDL after it delivers triglycerides to fat cells, transports cholesterol to various cells. Very low density lipoprotein (VLDL) transports triglycerides from the liver to fat cells - MSD Manual

The straight dope on cholesterol – Part II

The proteins that traffic collections of lipids are called apoproteins. Once bound to lipids they are called apolipoproteins, and the protein wrapped “vehicle” that transports the lipids are called lipoproteins. Many of you have probably heard this term before, but I’d like to ensure everyone really understands their important features. A crucial concept is that, for the most part, lipids go nowhere in the human body unless they are a passenger inside a protein wrapped vehicle called a lipoprotein. As their name suggests lipoproteins are part lipid and part protein. They are mostly spherical structures which are held together by a phospholipid membrane (which, of course, contains free cholesterol).
