Main ChEBI Ontology Automatic Xrefs Reactions Pathways Models
ChEBI Name ochratoxin A
ChEBI ID CHEBI:7719
Definition A phenylalanine derivative resulting from the formal condensation of the amino group of L-phenylalanine with the carboxy group of (3R)-5-chloro-8-hydroxy-3-methyl-1-oxo-3,4-dihydro-1H-2-benzopyran-7-carboxylic acid (ochratoxin α). It is among the most widely occurring food-contaminating mycotoxins, produced by Aspergillus ochraceus, Aspergillus carbonarius and Penicillium verrucosum.
