Avogadro’s lab: Investigating why molecules have different shapes

The shape of a molecule affects how it interacts with other molecules and that in turn can give rise to all kinds of interesting phenomena. One important area is how drugs work in the body. The drug will commonly interact with a larger molecule, such as a protein. This causes a chain of events which give the drug its specific medicinal properties.
