Chylomicron: A small fat globule composed of protein and lipid (fat). If LDL is not readily cleared from teh bloodstream, scavenger cells in the arteries take up the lipoprotein, leading to a buildup of cholesterol in the blood vessels, which increases the risk for cardiovascular disease. An enzyme attached to the cells that form the inner lining of blood vessels; it breaks down triglycerides into free fatty acids and glycerol. A buildup of fatty material (plaque) in the arteries, including those surrounding the heart. Why is LDL often referred to as bad cholesterol?

The lipoprotein int eh blood containing primarily cholesterol; elevated LDL is strongly linked to cardiovascular disease. Enzyme that hydrolyzes the ester bond between a fatty acid and glycerol in a triglyceride molecule. Chylomicrons, the least dense type of cholesterol transport molecules, contain apolipoprotein B-48, apolipoprotein C, and apolipoprotein E in their shells. The study includes in areas, such as clinical nutrition, community nutrition, public health and food policy and food science. Chylomicrons (from the Greek ÏÏ Î»ÏÏ, chylos, meaning juice (of plants or animals), and micron, meaning small particle), also known as ultra low-density lipoproteins (ULDL), are lipoprotein particles that consist of triglycerides (85â92%), phospholipids (6â12%), cholesterol (1â3%), and proteins (1â2%). no more than 1,500 calories a day.
