A Correct answer
Explanation

Phospholipids are the most abundant lipid class in blood plasma. They form the structural backbone of all lipoprotein particles (HDL, LDL, VLDL, chylomicrons) that transport lipids through the bloodstream. The amphipathic nature of phospholipids allows them to form stable spherical micelles that carry hydrophobic lipids in the aqueous blood plasma.
