Which type of lipoprotein transports the MAJORITY of cholesterol to cells for steroid hormone synthesis?

Lipoproteins are responsible for transporting lipids, including cholesterol, in the bloodstream. Among the various types of lipoproteins, low-density lipoprotein (LDL) specifically plays a crucial role in the delivery of cholesterol to the body's cells.

LDL is often referred to as "bad cholesterol" because it is associated with the transport of cholesterol that can lead to plaque buildup in arteries. However, its primary function is to supply cholesterol to peripheral tissues for use in various biological processes, including the synthesis of steroid hormones. Hormones such as cortisol, testosterone, and estrogen are synthesized from cholesterol, making its transport essential for endocrine function.

While high-density lipoprotein (HDL) is known for transporting cholesterol away from the tissues back to the liver for excretion or recycling, and very low-density lipoprotein (VLDL) primarily carries triglycerides, LDL's primary role of ferrying cholesterol directly to cells underlines its importance in hormone synthesis and overall cellular metabolism. Intermediate-density lipoprotein (IDL), on the other hand, is a transitional form in the metabolism of VLDL and has a lesser role in direct cholesterol delivery compared to LDL.

Thus, LDL is recognized as the type of lipoprotein responsible
