Examples for
Cheminformatics
Cheminformatics (also known as chemoinformatics or chemioinformatics) is a subfield of computational chemistry, utilizing chemical topology, graph theory and data mining for purposes such as drug discovery and substructure filtering. Use Wolfram|Alpha to explore cheminformatics properties, from graph invariants like Balaban's J-index or the Hosoya index to QSAR descriptors like the hydrogen donor count and longest chain.
Chemical Substructures
Find properties related to chemical substructures.
Find the largest common substructure of two molecules:
Find the longest chemical chain:
Find aromatic atoms:
Find hydrogen bond donors and acceptors:
Topological Indices
Topological indices are molecular descriptors computed directly from the chemical graph. Use Wolfram|Alpha to compute these graph invariant properties.
Compute a set of topological indices for a molecule:
Compute a particular topological descriptor:
