Dipole-dipole forces exist between polar regions of different molecules. The presence of a dipole means that the molecule has a partially positive end and a partially negative end. Oppositely charged partial charges attract each other, whereas like partial charges repel. In most cases, biological systems utilize a special type of dipole-dipole force known as hydrogen bonding (see the following section). (We said, “hydrogen bond,” not “hydrogen bomb” — there’s a big difference!)
