| + | Apolipoproteins are proteins that coat lipoprotein surface that binds lipids such as cholesterol, low-density lipoprotein (LDL), or high-density lipoproteins (HDL) in lipid metabolism. They function in the transport of such lipids in their structure that acts as a ligand to cell receptors and lipid transport proteins. <ref> Voet, D., Voet, J. G., & Pratt, C. W. (2016). Fundamentals of Biochemistry (5th ed.). Hoboken, NJ: John Wiley & Sons.</ref> They are important in the binding and transportation of lipids throughout the body, necessary in energy structural components, and nutrients. | ||
| + | Apolipoprotein A-I is a protein of APOA1 gene located on the 11th chromosome found in humans that is a component of HDL. Gene for APOA1 protein contains a total of 4 exons that is synthesized for the protein, used in lipid metabolism of HDL. <ref> APOA1 gene: MedlinePlus Genetics. (2020, August 18).

| - | Apolipoprotein A-I is a protein APOA1 gene in humans that is a component of HDL, which a form of good cholesterol in human's diet, used in the transport of cholesterol and phospholipids in the body through the bloodstream in the reverse transport of cholesterol from the tissues to the liver of hepatocytes. They promote cholesterol efflux, a pathway in transferring intracellular cholesterol to extracellular acceptors, from tissues and act as a cofactor for the lecithin cholesterol acyltransferase (LCAT). | ||
