RXNO Ontology

From Wikipedia, the free encyclopedia
Jump to navigation Jump to search

The RXNO Ontology is a formal ontology of chemical named reactions.[1] [2] It was originally developed at the Royal Society of Chemistry (RSC) and is associated with the Open Biomedical Ontologies Foundry. The RXNO ontology unifies several previous attempts to systematize chemical reactions including the Merck Index and the hierarchy of Carey, Laffan, Thomson and Williams.[3][4]

Major Reaction Categories[edit]

The twelve top-level reaction categories proposed by Carey, Laffan, Thompson and Williams are given in the table below, together with their RXNO ontology identifiers and the equivalent wikipedia categories where applicable.[3]

2 Acylation and related processes
3 Carbon-Carbon bond formation RXNO:0000002 Category:Carbon-carbon bond forming reactions
4 Heterocycle forming reactions RXNO:0000349 Category:Heterocycle forming reactions
5 Protection reactions RXNO:0000078
6 Deprotection reactions RXNO:0000203
