How does HDL interact with other Lipoproteins in Catalysis?
HDL interacts with other lipoproteins through a process called cholesterol efflux. It receives cholesterol from low-density lipoprotein (LDL) and very-low-density lipoprotein (VLDL) particles, which is then esterified and transported back to the liver. This interaction is catalyzed by enzymes like Cholesteryl Ester Transfer Protein (CETP), which facilitates the transfer of cholesteryl esters and triglycerides between lipoproteins, thereby maintaining lipid homeostasis.
