Does the human body naturally produce small ldl particles? why or what are the functions of small ldl cholesterols in the human body?

Yes: Ldl-cholesterol is important for the transport of cholesterol in the blood. Small dense particles still transport cholesterol, they are just more prone to be deposited in arterial walls compared to the lighter, less dense particles.
Dr. Dean Giannone

LDL function.: LDL cholesterol does have a function in our bodies, so in some respects is necessary. The small dense LDL particles to which you refer, however, are more atherogenic than the other large buoyant LDL particles. Niacin supplementation can improve your LDL subtype, changing small dense LDL to large buoyant LDL.
