Triglycerides and cholesteryl esters are transported in the core of plasma lipoproteins. The intestine secretes dietary fat in chylomicrons, lipoproteins that transport triglyceride to tissues for storage. Dietary cholesterol is transported to the liver by chylomicron remnants which are formed from chylomicrons.
In order for lipids to be transported in the bloodstream without clumping together, they need to be packaged into small particles called lipoproteins. Lipoproteins are soluble in blood, and allow cholesterol and triglycerides to be moved with ease through the bloodstream.
