Lipoproteins are like suitcases that move cholesterol, fatty acid remnants, triglycerides, and phospholipids from one place to another. Given what you know about the insolubility of lipids in water and the unique structures of each of these molecules, which of the 4 kinds of aforementioned lipids would you predict to be on the outside of a lipoprotein clump, bathed in the water-based fluid portion of blood and why?
