Hepatic lipase taken up from the plaque by SR-B1 receptors, which convert HDL3 to HDL2 which contains higher concentrations of free fatty acids. HDL2 can then interact with LDL and IDL by transferring over fatty acids that have accumulated in the plaque.

The human body contains two inactive forms of HL. One inactive form is found on the liver bound to
