Properties

9 of its own, and 27 it inherits. Each says what kind of value it takes.

Its own9
PropertyValueWhat it means
chemicalRolePendingValue: DefinedTerm

A role played by the BioChemEntity within a chemical context.

inChIPendingValue: Text

Non-proprietary identifier for molecular entity that can be used in printed and electronic data sources thus enabling easier linking of diverse data compilations.

inChIKeyPendingValue: Text

InChIKey is a hashed version of the full InChI (using the SHA-256 algorithm).

iupacNamePendingValue: Text

Systematic method of naming chemical compounds as recommended by the International Union of Pure and Applied Chemistry (IUPAC).

molecularFormulaPendingValue: Text

The empirical formula is the simplest whole number ratio of all the atoms in a molecule.

molecularWeightPendingValue: QuantitativeValue or Text

This is the molecular weight of the entity being described, not of the parent. Units should be included in the form '<Number> <unit>', for example '12 amu' or as '<QuantitativeValue>.

monoisotopicMolecularWeightPendingValue: QuantitativeValue or Text

The monoisotopic mass is the sum of the masses of the atoms in a molecule using the unbound, ground-state, rest mass of the principal (most abundant) isotope for each element instead of the isotopic average mass. Please include the units in the form '<Number> <unit>', for example '770.230488 g/mol' or as '<QuantitativeValue>.

potentialUsePendingValue: DefinedTerm

Intended use of the BioChemEntity by humans.

smilesPendingValue: Text

A specification in form of a line notation for describing the structure of chemical species using short ASCII strings. Double bond stereochemistry \ indicators may need to be escaped in the string in formats where the backslash is an escape character.

PropertyValueWhat it means
associatedDiseasePendingValue: MedicalCondition, PropertyValue or URL

Disease associated to this BioChemEntity. Such disease can be a MedicalCondition or a URL. If you want to add an evidence supporting the association, please use PropertyValue.

bioChemInteractionPendingValue: BioChemEntity

A BioChemEntity that is known to interact with this item.

bioChemSimilarityPendingValue: BioChemEntity

A similar BioChemEntity, e.g., obtained by fingerprint similarity algorithms.

biologicalRolePendingValue: DefinedTerm

A role played by the BioChemEntity within a biological context.

fundingValue: Grant

A Grant that directly or indirectly provide funding or sponsorship for this item. See also ownershipFundingInfo.

hasBioChemEntityPartPendingValue: BioChemEntity

Indicates a BioChemEntity that (in some sense) has this BioChemEntity as a part.

hasMolecularFunctionPendingValue: DefinedTerm, PropertyValue or URL

Molecular function performed by this BioChemEntity; please use PropertyValue if you want to include any evidence.

hasRepresentationPendingValue: PropertyValue, Text or URL

A common representation such as a protein sequence or chemical structure for this entity. For images use schema.org/image.

isEncodedByBioChemEntityPendingValue: Gene

Another BioChemEntity encoding by this one.

isInvolvedInBiologicalProcessPendingValue: DefinedTerm, PropertyValue or URL

Biological process this BioChemEntity is involved in; please use PropertyValue if you want to include any evidence.

isLocatedInSubcellularLocationPendingValue: DefinedTerm, PropertyValue or URL

Subcellular location where this BioChemEntity is located; please use PropertyValue if you want to include any evidence.

isPartOfBioChemEntityPendingValue: BioChemEntity

Indicates a BioChemEntity that is (in some sense) a part of this BioChemEntity.

taxonomicRangePendingValue: DefinedTerm, Taxon, Text or URL

The taxonomic grouping of the organism that expresses, encodes, or in some way related to the BioChemEntity.

From Thing14
PropertyValueWhat it means
additionalTypeValue: Text or URL

An additional type for the item, typically used for adding more specific types from external vocabularies in microdata syntax. This is a relationship between something and a class that the thing is in. Typically the value is a URI-identified RDF class, and in this case corresponds to the use of rdf:type in RDF. Text values can be used sparingly, for cases where useful information can be added without their being an appropriate schema to reference. In the case of text values, the class label should follow the schema.org style guide.

alternateNameValue: Text

An alias for the item.

descriptionValue: Text or TextObject

A description of the item.

digital.org.aiValue: Number

Digital maturity score from 0.0 (fully analog/manual) to 1.0 (fully digital/autonomous). Indicates the degree to which an entity operates digitally.

disambiguatingDescriptionValue: Text

A sub property of description. A short description of the item used to disambiguate from other, similar items. Information from other properties (in particular, name) may be necessary for the description to be useful for disambiguation.

identifierValue: PropertyValue, Text or URL

The identifier property represents any kind of identifier for any kind of Thing, such as ISBNs, GTIN codes, UUIDs etc. Schema.org provides dedicated properties for representing many of these, either as textual strings or as URL (URI) links. See background notes for more details.

imageValue: ImageObject or URL

An image of the item. This can be a URL or a fully described ImageObject.

mainEntityOfPageValue: CreativeWork or URL

Indicates a page (or other CreativeWork) for which this thing is the main entity being described. See background notes for details.

nameValue: Text

The name of the item.

ownerValue: Organization or Person

A person or organization who owns this Thing.

potentialActionValue: Action

Indicates a potential Action, which describes an idealized action in which this thing would play an 'object' role.

sameAsValue: URL

URL of a reference Web page that unambiguously indicates the item's identity. E.g. the URL of the item's Wikipedia page, Wikidata entry, or official website.

subjectOfValue: CreativeWork or Event

A CreativeWork or Event about this Thing.

urlValue: URL

URL of the item.
