Understanding the structure and evolution of disks surrounding young low-mass stars is one of the key issues to study the process of planet formation. Observation of molecular lines is a useful tool to constrain the disks physical structure, as different molecules sample different physical conditions. Beside the abundant CO, several other molecules have been detected in the outer part of the disks in the millimeter domain (e.g. HCO+, H2CO, CS, HCN, CN...). In this talk I will present results obtained in the last few years with (sub-)millimiter telescopes, and I will review some recent ALMA outcomes.
