ALMA has revealed that planet-forming disks host a rich chemistry, with molecules displaying complex radial and vertical emission profiles. I review some of the chemical disk structures discovered so far, what they have taught us about the ongoing chemical evolution during planet-formation, and the distribution of volatiles in disks. I also discuss what additional observations are needed to further link disk chemistry to the compositions of nascent planets.
