Phospholipids and lipoproteins
WebSep 19, 2024 · The major function of lipoproteins is to transport triacylglycerols, cholesterol, and phospholipids around the body. Chylomicrons Chylomicrons are synthesized in the intestine and transport dietary triacylglycerols to skeletal muscle and adipose tissue, and dietary cholesterol to the liver. WebLipoproteins. After ingestion, cholesterol and lipids are transported in the blood using micelle-like structures called lipoproteins. A micelle is a sphere consisting of a single layer of phospholipids. A lipoprotein is essentially a micelle with certain proteins embedded within the phospholipid monolayer. As the phospholipid hydrophobic tails ...
