Chemical similarity refers to the concept of comparing the chemical structures, properties, or behaviors of different molecules to determine how alike they are. This can involve evaluating various aspects, including: 1. **Structural Similarity**: Molecules may be considered chemically similar if they share a similar arrangement of atoms, functional groups, or overall 3D conformation. Structural similarity can be quantified using methods such as graph theory or molecular descriptors.
