HUMAN NUTRITION

Detailed explanation-1: -HDL, LDL, and VLDL are lipoproteins. They are a combination of fat (lipid) and protein. The lipids need to be attached to the proteins so they can move through the blood.

Detailed explanation-2: -Lipoproteins are round particles made of fat (lipids) and proteins that travel in your bloodstream to cells throughout your body.

Detailed explanation-3: -Fats are large molecules made of two types of molecules, glycerol and some type of fatty acid. The fatty acid has a long chain of carbon and hydrogen, usually referred to as the hydrocarbon tail, with a carboxyl group head. (The carboxyl group is why its called an acid).

Detailed explanation-4: -Blood lipids (or blood fats) are lipids in the blood, either free or bound to other molecules. They are mostly transported in a protein capsule, and the density of the lipids and type of protein determines the fate of the particle and its influence on metabolism.
