isopatulin	CHEBI_145111	[A furopyran and lactone that is (2H-pyran-3(6H)-ylidene)acetic acid which is substituted by hydroxy groups at positions 4 an 6 and in which the hydroxy group at position 4 has condensed with the carboxy group to give the corresponding bicyclic lactone. Also known as neopatulin, it is a mycotoxic substance produced by Aspergillus and Penicillium species.]
furopyran	CHEBI_74927	[Any organic heterobicyclic compound containing ortho-fused furan and pyran rings.]
lactol	CHEBI_38131	[Cyclic hemiacetals formed by intramolecular addition of a hydroxy group to an aldehydic or ketonic carbonyl group. They are thus 1-oxacycloalkan-2-ols or unsaturated analogues.]
