Glucose, a carbohydrate, readily dissolves in your bloodstream due to its polar -OH groups. Cholesterol and triglycerides—both lipids—are packaged inside the waterproof spaces of lipoproteins so they can enter the bloodstream. Use the molecular models from the activity to compare the chemical compositions and structures of glucose, cholesterol, and triglycerides. Construct an explanation for how the compositions and structures of these carbon-based molecules are related to the way they interact with your bloodstream. How is glucose different from cholesterol and triglycerides? How does this difference affect whether the molecule can dissolve in blood which is mostly water?
