Apo A is mainly found in HDL and has many positive physiological effects on the body, such as reversing the transport of cholesterol and triglycerides, the decrease of which leads to an increased risk of atherosclerosis formation. Apolipoprotein B is mainly found in LDL, and its elevation also leads to a higher risk of atherosclerosis formation.
