Lipoproteins

Lipoproteins are complex particles that have a central hydrophobic core of non-polar lipids, primarily cholesteryl esters and triglycerides. This hydrophobic core is surrounded by a hydrophilic membrane consisting of phospholipids, free cholesterol, and apolipoproteins. Plasma lipoproteins are divided into seven classes based on size, lipid composition, and apolipoproteins. WebAs has been mentioned above, lipoproteins are an assembly of phospholipids and proteins that carry triglycerides and cholesterol in the blood. Low-Density Lipoprotein (LDL) is lower in protein and higher in lipid content, and High-Density Lipoprotein (HDL) has more apoproteins which increases this particle’s overall density. tintamarre vichy
