Uses Mixins

• mixin: PhysicalEssence - Semantic mixin concept. Pertains to entities that have physical properties such as mass, volume, or charge.
• mixin: ChemicalOrDrugOrTreatment
• mixin: ChemicalEntityOrGeneOrGeneProduct - A union of chemical entities and children, and gene or gene product. This mixin is helpful to use when searching across chemical entities that must include genes and their children as chemical entities.
• mixin: ChemicalEntityOrProteinOrPolypeptide - A union of chemical entities and children, and protein and polypeptide. This mixin is helpful to use when searching across chemical entities that must include genes and their children as chemical entities.

Children

• ChemicalMixture - A chemical mixture is a chemical entity composed of two or more molecular entities.

Attributes

Own

• available from _0..*
  • Range: DrugAvailabilityEnum
• has chemical role _0..*
  • Description: A role is particular behaviour which a chemical entity may exhibit.
  • Range: ChemicalRole
• is toxic _0..1
  • Range: Boolean
• max tolerated dose _0..1
  • Description: The highest dose of a drug or treatment that does not cause unacceptable side effects. The maximum tolerated dose is determined in clinical trials by testing increasing doses on different groups of people until the highest dose with acceptable side effects is found. Also called MTD.
  • Range: String
• trade name _0..1
  • Range: ChemicalEntity

Inherited from entity:

• id _1..1
  • Description: A unique identifier for an entity. Must be either a CURIE shorthand for a URI or a complete URI
  • Range: String
  • in subsets: (translator_minimal)
• iri _0..1
  • Description: An IRI for an entity. This is determined by the id using expansion rules.
  • Range: IriType
  • in subsets: (translator_minimal,samples)
• category _0..*
  • Description: Name of the high level ontology class in which this entity is categorized. Corresponds to the label for the biolink entity type class.
• In a neo4j database this MAY correspond to the neo4j label tag.
• In an RDF database it should be a biolink model class URI. This field is multi-valued. It should include values for ancestors of the biolink class; for example, a protein such as Shh would have category values biolink:Protein, biolink:GeneProduct, biolink:MolecularEntity, … In an RDF database, nodes will typically have an rdf:type triples. This can be to the most specific biolink class, or potentially to a class more specific than something in biolink. For example, a sequence feature f may have a rdf:type assertion to a SO class such as TF_binding_site, which is more specific than anything in biolink. Here we would have categories {biolink:GenomicEntity, biolink:MolecularEntity, biolink:NamedThing}
  • Range: CategoryType
  • in subsets: (translator_minimal)
• type _0..*
  • Range: String
• description _0..1
  • Description: a human-readable description of an entity
  • Range: NarrativeText
  • in subsets: (translator_minimal)
• has attribute _0..*
  • Description: connects any entity to an attribute
  • Range: Attribute
  • in subsets: (samples)

Inherited from gene product mixin:

• xref _0..*
  • Description: Alternate CURIEs for a thing

Inherited from macromolecular machine mixin:

• name _0..1
  • Description: A human-readable name for an attribute or entity.
  • Range: LabelType
  • in subsets: (translator_minimal,samples)

Inherited from named thing:

• provided by _0..*
  • Description: The value in this node property represents the knowledge provider that created or assembled the node and all of its attributes. Used internally to represent how a particular node made its way into a knowledge provider or graph.
  • Range: String
• category _0..*
  • Description: Name of the high level ontology class in which this entity is categorized. Corresponds to the label for the biolink entity type class.
