| Definition: Any bioactive molecule that is not a peptide, DNA, or RNA. Generally these are non-polymeric, but complex carbohydrates are not explicitly modeled as classes in this version of the ontology, thus are forced into this class. Comment: Recently, a number of small molecule databases have become available to cross-reference from this class. Examples: glucose, penicillin, phosphatidylinositol |
