Diversity

Definition

Diversity refers to the variety and differences found in a particular set, particularly in the context of chemical compounds. In combinatorial chemistry, diversity is crucial because it allows for the generation of a wide array of compounds that can lead to discovering new drugs and therapeutic agents. This range of different structures increases the chances of finding molecules with desirable biological activity.
