Lipoproteins,illustration. These are low density lipoprotein (LDL),or 'bad' cholesterol,molecules. They consist of a core of esterified cholesterol molecules surrounded by a shell (pink) of unesterified cholesterol and phospholipids. The complex structure includes carrier proteins (green) known as apo-B proteins,which assist transport in the blood. When there are high levels of LDL cholesterol in the blood it builds up on the sides of blood vessels hardening them,a condition named atherosclerosis. This narrows the blood vessels and may block them | |
