They are designated as alpha-, beta-, gamma-, and delta-tocopherol depending on the number and position of additional methyl substituents on the aromatic ring. Tocopherols occur in vegetable oils and vegetable oil products, almost exclusively with R,R,R configuration. Tocotrienols differ from tocopherols only in having three double bonds in the hydrocarbon chain.</obo_purl:IAO_0000115> <rdfs:label rdf:datatype="http://www.w3.org/XML/1998/namespacestring">tocopherol</rdfs:label> <rdfs:label>tocopherol</rdfs:label> <oboinowl_gen:id>CHEBI:27013</oboinowl_gen:id> <obo_purl:IAO_0000412 rdf:resource="http://purl.obolibrary.org/obo/chebi.owl"/> </owl:Class> <rdf:Description rdf:about="http://purl.obolibrary.org/obo/CHEBI_145207"> <rdfs:subClassOf> <rdf:Description rdf:about="http://purl.obolibrary.org/obo/CHEBI_27013"> <metadata_def:mappingSameURI rdf:resource="http://purl.obolibrary.org/obo/CHEBI_27013"/> </rdf:Description> </rdfs:subClassOf> </rdf:Description> <rdf:Description rdf:about="http://purl.obolibrary.org/obo/CHEBI_168306"> <rdfs:subClassOf rdf:resource="http://purl.obolibrary.org/obo/CHEBI_27013"/> </rdf:Description> <rdf:Description rdf:about="http://purl.obolibrary.org/obo/CHEBI_180962"> <rdfs:subClassOf rdf:resource="http://purl.obolibrary.org/obo/CHEBI_27013"/> </rdf:Description> <rdf:Description rdf:about="http://purl.obolibrary.org/obo/CHEBI_18185"> <rdfs:subClassOf rdf:resource="http://purl.obolibrary.org/obo/CHEBI_27013"/> </rdf:Description> <rdf:Description rdf:about="http://purl.obolibrary.org/obo/CHEBI_182172"> <rdfs:subClassOf rdf:resource="http://purl.obolibrary.org/obo/CHEBI_27013"/> </rdf:Description> <rdf:Description rdf:about="http://purl.obolibrary.org/obo/CHEBI_22470"> <rdfs:subClassOf rdf:resource="http://purl.obolibrary.org/obo/CHEBI_27013"/> </rdf:Description> <rdf:Description rdf:about="http://purl.obolibrary.org/obo/CHEBI_47771"> <rdfs:subClassOf rdf:resource="http://purl.obolibrary.org/obo/CHEBI_27013"/> </rdf:Description> <rdf:Description rdf:about="http://purl.obolibrary.org/obo/CHEBI_47772"> <rdfs:subClassOf rdf:resource="http://purl.obolibrary.org/obo/CHEBI_27013"/> </rdf:Description> <rdf:Description rdf:about="http://purl.obolibrary.org/obo/CHEBI_70411"> <rdfs:subClassOf rdf:resource="http://purl.obolibrary.org/obo/CHEBI_27013"/> </rdf:Description> <rdf:Description rdf:about="http://purl.obolibrary.org/obo/CHEBI_93909"> <rdfs:subClassOf rdf:resource="http://purl.obolibrary.org/obo/CHEBI_27013"/> </rdf:Description> </rdf:RDF>
