ChEBI Get Ontology Children

Get the ontology children (is-a, has-part, has-functional-parent, etc.) of a ChEBI compound. ChEBI uses a rich ontology with relationships like 'is a', 'has part', 'has role', 'has functional parent', and 'is conjugate base/acid of'. This enables navigation of the chemical classification hierarchy. Example: CHEBI:15365 (aspirin) children include NCX-4040 (has functional parent), acetylsalicylate (conjugate base), and Yosprala (has part).
