CHEBI:7719 - ochratoxin A

ChEBI IDCHEBI:7719
ChEBI Nameochratoxin A
Stars
DefinitionA 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.
