Question

Quizplus · Accepted Answer

Oxidized LDL, not all forms of LDL, is known to be unhealthy because it can lead to the formation of plaque in the arteries. This plaque buildup can contribute to cardiovascular disease, heart attacks, and strokes. The cholesterol carried by oxidized LDL is taken up by certain arterial cells and deposited in plaque, leading to the proliferation of smooth muscle cells and the accumulation of macrophages. This ultimately leads to the formation of a complex atherosclerotic plaque. HDL, not hydrolyzed HDL, is considered a healthy lipoprotein as it helps remove excess cholesterol from the body. VLDLs do transport cholesterol, but primarily to other tissues for energy production or to adipose tissue for storage. The liver plays a significant role in cholesterol metabolism by synthesizing and producing various types of lipoproteins, including VLDL.
