LP15400-2   Apolipoprotein B
Apolipoproteins are a family of proteins involved in cholesterol transport and metabolism. Apoliprotein B is a primary protein component of low-density lipoprotein (LDL or "bad" cholesterol), very low-density lipoprotein (VLDL) and chylomicrons and is encoded by the APOB gene. The liver produces the B-100 form, which includes a region that is recognized by the ApoB/E LDL receptor, and the small intestine produces B-48, which is cleaved from B-100 and does not include the receptor region. Deficiency of apolipoprotein B is associated with low LDL levels and fat malabsorption, while high levels of circulating apolipoprotein B-100, which can be a result of a defect in the ApoB/E receptor ligand, are associated with high cholesterol and risk for coronary artery disease [UniProt: P04114].

LP31988-6   Apolipoprotein A-I
The major protein component of high density lipoproteins. It is instrumental in promoting efflux of cholesterol from extrahepatic tissue to the liver where it is metabolized and excreted from the body. The compound is the activator of lecithin-cholesterol acyltransferase which forms cholesteryl esters in HDL. The gene for this apolipoprotein is found on the long arm of chromosome 11.

LP31988-6   Apolipoprotein A-I
Apolipoproteins are a family of proteins involved in cholesterol transport and metabolism. Apoliprotein A is an important component of high-density lipoprotein (HDL or "good" cholesterol) and has several subtypes, including A-I and A-II, which are encoded by the APOA1 and APOA2 genes, respectively. A-I and A-II are the primary protein components of HDL. Deficiency of apolipoprotein A-I is associated with low HDL levels [], while deficiency of A-II is not associated with significant changes in HDL or other lipid levels [UniProt: P02652].
