Common NameGalactonolactone
DescriptionGalactonolactone is a lactone formed from galactonic acid/galactonate. There are different isomers of galactonolactone, including structural isomers with different numbers of carbons in the lactone ring (up to 6 carbons), and also D/L enantiomers for certain structural isomers. (ChEBI, PubChem, inferred from compound structures) In E. coli, both the D and L enantiomers of galactono-1,4-lactone (with 4 carbons in the lactone ring) can be found. (EcoCyc) D-galactono-1,5-lactone (with 5 carbons in the lactone ring) has been shown to have a strong inhibitory effect on E. coli beta-galactosidase. (PMID 3109465 )
