Apolipoprotein A-1 (APO A) and Apolipoprotein B (APO B)

Apolipoprotein A-I (apo A-I) is the major structural and functional protein component of high-density lipoprotein (HDL), or good cholesterol in plasma. It accounts for approximately 70% of HDL. Apo A-I activates lecithin cholesterol acyltransferase (LCAT) which catalyzes the esterification of cholesterol. The resulting esterified cholesterol can then be transported to the liver, metabolized, and excreted. […]
