Lipoprotein complexes are made of phospholipids, proteins, and cholesterol. The phospholipids form a single layer on the outside that surround fats and cholesterol on the inside. Their function is to transport hydrophobic fats and cholesterol in aqueous blood. a) Explain why fats and cholesterol must be contained within the lipoprotein complex to be transported in the blood. b) Explain why glucose and amino acids do not require a lipoprotein complex to be transported in the blood. c) Where is the non-polar region in the complex? What functional groups make the external portion of the complex hydrophilic?

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?

Lipoproteins are relatively large, spherical clumps of protein and lipid molecules that circulate in the blood of mammals. They are like suitcases that move cholesterol, fatty acid remnants, triglycerides, and phospholipids from one place to another in the body. Given what you know about the insolubility of lipids in water, which of the three kinds of lipids would you predict to be on the outside of a lipoprotein clump, bathed in the fluid portion of blood?
Cholesterol is transported in the bloodstream in lipoprotein particles. There are several classes of lipoprotein particles, but one of the most important classes is called low-density lipoprotein (LDL) particles. LDL particles are composed of a large protein called apolipoprotein, as well as thousands of cholesterol molecules and phospholipids. Part of the apolipoprotein forms the surface of the particle and faces the aqueous phase. Other parts of apolipoprotein face the inside of the particle and interact with lipids and cholesterol. What is the most likely location of phospholipids in LDL particles? A. Within the hydrophobic core of the particle. B. In a lipid bilayer. C. On the surface with their fatty acid tails interacting with the hydrophilic domain of apolipoprotein. D. On the surface with their polar head groups interacting with cholesterol. E. On the surface with their polar head groups interacting with the aqueous environment.
