The vitamers in this class consists of a chroman-6-ol core which is substituted at position 2 by a methyl group and (also at position 2) either a saturated or a triply-unsaturated hydrocarbon chain consisting of three isoprenoid units. The major function of vitamin E is to act as a natural antioxidant by scavenging free radicals and molecular oxygen.</obo_purl:IAO_0000115> <obo_purl:IAO_0000118 xml:lang="en">d-alpha-tocopherol</obo_purl:IAO_0000118> <obo_purl:IAO_0000118 xml:lang="en">vitamin e</obo_purl:IAO_0000118> <obo_purl:IAO_0000412 rdf:resource="http://purl.obolibrary.org/obo/chebi.owl"/> <obo_purl:IAO_0000412 rdf:resource="http://langual.org"/> <ns0:hasDbXref rdf:resource="http://www.langual.org/langual_thesaurus.asp?termid=B3753"/> <ns0:hasDbXref rdf:resource="http://www.langual.org/langual_thesaurus.asp?termid=B3784"/> <ns1:id>CHEBI:33234</ns1:id> <ns2:prefLabel>vitamin E</ns2:prefLabel> <ns3:mappingLoom>vitamine</ns3:mappingLoom> <ns4:mappingSameURI rdf:resource="http://purl.obolibrary.org/obo/CHEBI_33234"/> </owl:Class> <rdf:Description rdf:about="http://purl.obolibrary.org/obo/CHEBI_27013"> <rdfs:subClassOf> <rdf:Description rdf:about="http://purl.obolibrary.org/obo/CHEBI_33234"> <ns0:mappingSameURI rdf:resource="http://purl.obolibrary.org/obo/CHEBI_33234"/> </rdf:Description> </rdfs:subClassOf> </rdf:Description> <rdf:Description rdf:about="http://purl.obolibrary.org/obo/CHEBI_32321"> <rdfs:subClassOf rdf:resource="http://purl.obolibrary.org/obo/CHEBI_33234"/> </rdf:Description> <rdf:Description rdf:about="http://purl.obolibrary.org/obo/CHEBI_33235"> <rdfs:subClassOf rdf:resource="http://purl.obolibrary.org/obo/CHEBI_33234"/> </rdf:Description> <rdf:Description rdf:about="http://purl.obolibrary.org/obo/FOODON_03413786"> <rdfs:subClassOf rdf:resource="http://purl.obolibrary.org/obo/CHEBI_33234"/> </rdf:Description> <rdf:Description rdf:about="http://purl.obolibrary.org/obo/FOODON_03413787"> <rdfs:subClassOf rdf:resource="http://purl.obolibrary.org/obo/CHEBI_33234"/> </rdf:Description> </rdf:RDF>
