In the postgenomic era new technologies are emerging for global analysis of protein function. The introduction of active site-directed chemical probes for enzymatic activity profiling in complex mixtures, known as activity-based proteomics has greatly accelerated functional annotation of proteins.

Lipases are responsible for the hydrolysis of acylglycerols and cholesteryl esters in animals, plants, and microorganisms. In this chapter we describe a tool for the concomitant analysis of lipases in complex proteomes. For this purpose, the target enzymes are selectively
