Familial lipoprotein lipase deficiency is a group of rare genetic disorders in which a person lacks a protein needed to break down fat molecules. The disorder causes a large amount of fat to build up in the blood. Familial lipoprotein lipase deficiency is caused by a defective gene that is passed down through families. People with this condition lack an enzyme called lipoprotein lipase. Without this enzyme, the body cannot break down fat from digested food.

Lipoprotein lipase LPL is an extracellular enzyme on the vascular endothelial surface that degrades circulating triglycerides in the bloodstream. These triglycerides are embedded in very low-density lipoproteins VLDL and chylomicrons traveling through the bloodstream. The role of lipoprotein lipase is significant in understanding the pathophysiology of type one familial dyslipidemias, or hyperchylomicronemia, and its clinical manifestations. LPL also plays an essential role in understanding the cardiac pharmacology of fibrates as a class of medications and in managing patients with high levels of serum triglycerides. This review will explore lipoprotein lipase's function, pathophysiology, and clinical relevance. The structure of lipoprotein lipase is similar to the enzymes in the lipase family and comprises two distinct regions.

Palmitoyl protein thioesterase Ubiquitin carboxy-terminal hydrolase L1 4-hydroxybenzoyl-CoA thioesterase. You may want to discuss your diet needs with your provider and a registered dietitian, lipoprotein lipase.

It is a water-soluble enzyme that hydrolyzes triglycerides in lipoproteins , such as those found in chylomicrons and very low-density lipoproteins VLDL , into two free fatty acids and one monoacylglycerol molecule:. It is also involved in promoting the cellular uptake of chylomicron remnants , cholesterol-rich lipoproteins, and free fatty acids. In brief, LPL is secreted from heart, muscle and adipose parenchymal cells as a glycosylated homodimer, after which it is translocated through the extracellular matrix and across endothelial cells to the capillary lumen. After translation, the newly synthesized protein is glycosylated in the endoplasmic reticulum. Homodimerization is required before LPL can be secreted from cells.

This enzyme is found primarily on the surface of cells that line tiny blood vessels capillaries within muscles and in fatty adipose tissue. Lipoprotein lipase plays a critical role in breaking down fat in the form of triglycerides, which are carried from various organs to the blood by molecules called lipoproteins. Lipoprotein lipase breaks down triglycerides carried by two different types of lipoproteins, which bring fat to the bloodstream from different organs. Fat from the intestine, which is taken in from the diet, is transported to the bloodstream by lipoproteins called chylomicrons. Another type of lipoprotein called very low density lipoprotein VLDL carries triglycerides from the liver to the bloodstream. When lipoprotein lipase breaks down triglycerides, the fat molecules are used by the body as energy or stored in fatty tissue for later use. More than mutations in the LPL gene have been found to cause familial lipoprotein lipase deficiency.

Twenty grams of fat is equal to one of the following: Two 8-ounce milliliters glasses of whole milk 4 teaspoons 9. Chromosome 8 mouse [2]. Fibrates, such as fenofibrate, bezafibrate, and gemfibrozil, work by activating peroxisome proliferator-activated receptor alpha PPAR-alpha and upregulating lipoprotein lipase. Endocr Pract. Lipoprotein lipase breaks down triglycerides carried by two different types of lipoproteins, which bring fat to the bloodstream from different organs. Recent x-ray crystallography and biochemical experiments have provided more structural evidence revealing that lipoprotein lipase can be active as a monomer. Function Lipoprotein lipase is an enzyme that degrades circulating triglycerides in the bloodstream. A high adipose tissue LPL response to a high-carbohydrate diet may predispose toward fat gain.
