WebThe HDL particle is synthesized mainly by the liver, and also by the intestines. When excess cholesterol occurs in extra-hepatic tissues, it is picked up by HDLs by a process called reverse cholesterol transport. Apo A-I is the vital and defining protein of the HDL. Each HDL particle contains 2–4 molecules of Apo A-I.
