Q1. In one beaker you mix triglycerides with the water. In a second beaker you mix phospholipids with the water. You then let the contents of the beakers settle. Sketch a diagram that illustrates how you would expect the triglyceride and phospholipid molecules to interact with the water. Be sure to indicate structures, if any that might form as a result of these interactions.
