For example, one biochemical process in our body, inside the cells of our body, is the biosynthesis of proteins. And as a result of the properties of water, that protein is able to actually obtain its final three dimensional shape. And we'll discuss that in much more detail in a future lecture. In this lecture, we're going to focus on two important properties of water, and we're going to see how these two properties lead to an effect known as the hydrophobic effect. So let's begin by discussing property number one, the fact that water is a polar molecule. It contains an electric dipole moment.
