Decide whether each molecule in the table below could be found embedded in the outer surface of a cell membrane. For each molecule that could, decide whether the outside of the cell would lie to the right or left of the molecule as drawn. Note for advanced students: none of these molecules are actually found in cell membranes. Your goal is to use the principles of biochemistry to decide whether they could be, if for example they were synthesized and studied as drug candidates.
