ChemFOnt

ChemFOnt describes functions and actions of over 341,000 biologically significant chemicals in a hierarchical ontology compatible with the Web Ontology Language (OWL) for computational integration.

Key Features:

• Coverage: ChemFOnt encompasses over 341,000 chemicals including primary metabolites, secondary metabolites, natural products, food chemicals, synthetic additives, drugs, herbicides, pesticides, and environmental chemicals.
• OWL compatibility: The ontology is formatted for the Web Ontology Language (OWL) to enable integration into computational frameworks and databases.
• Hierarchical structure: Organized into four functional aspects, 12 super-categories, 173,705 functional terms, and 4,825 structure-based chemical classes.
• Relationship network: Includes approximately 3.9 million protein-chemical relationships and approximately 10.3 million chemical-functional relationships.
• FAIR compliance: Curated to adhere to the FAIR principles (Findable, Accessible, Interoperable, Reusable) for standardized chemical function annotation.

Scientific Applications:

• Data enrichment: Integration with omics datasets and analytical software generates machine-readable chemical-functional and protein-chemical relationships to enhance analyses.
• Inference generation: Enables inference of direct and indirect chemical interactions and effects to support hypothesis generation and testing.
• Cross-disciplinary integration: Standardizes chemical function terminology for use across metabolomics, exposomics, metagenomics, genomics, proteomics, and chemistry databases and tools.

Methodology:

Distributed in OWL format to permit incorporation of the ontology into databases and software.
