Apolipoprotein A-I
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. [1] 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. [2]
