Description
Apolipoprotein A-I is the major structural and functional protein component of high density lipoprotein (HDL, good cholesterol) in plasma. In normal plasma, Apo AI levels range from 90-130 mg per 100 ml. 75% of Apo A in HDL is Apo AI. Levels of Apo AI are inversely related to the risk of coronary heart disease. Apo AI is also thought to activate LCAT (lecithin cholesterol acyl tranferase)
