What are proteins containing particles that transport lipids in the blood called?

Proteins that transport lipids in the blood are called lipoproteins. These complexes consist of lipids and proteins, allowing for the solubilization and transport of hydrophobic lipids like cholesterol and triglycerides through the aqueous environment of the bloodstream. Common types of lipoproteins include low-density lipoprotein (LDL) and high-density lipoprotein (HDL), each playing different roles in lipid metabolism and cardiovascular health.
