CETP Moving Cholesterol from HDL to LDL (image) DOE/Lawrence Berkeley National Laboratory Caption (1) CETP penetrates HDL to its cholesterol core. (2) Upon interaction with LDL/VLDL, molecular forces cause the formation of pores at either end of CETP. (3) These pores connect with CETP's central cavities to form a tunnel for the transfer of cholesterol to LDL/VLDL, which (4) reduces HDL in size.
