Metabolite Identification
Common NameD-galactono-1,5-lactone
DescriptionD-galactono-1,5-lactone is a lactone and a metabolite involved in various biochemical pathways. Its chemical structure features a five-membered lactone ring derived from D-galactonic acid, contributing to its role as a transition state analog in enzymatic reactions (PMID:26291713 ). The compound has been utilized in organic synthesis, such as in the condensation reactions with thiocarbohydrazide to produce 3-(D-alditol-1-yl)-4-amino-5-mercapto-1,2,4-triazoles, with microwave-assisted methods enhancing the reaction efficiency (PMID:16629125 ). Additionally, D-galactono-1,5-lactone serves as a precursor for the synthesis of gamma-sugar-amino acid analogues, which can be prepared through a series of chemical transformations (PMID:16616901 ). Furthermore, it has been shown that D-galactono-1,5-lactone exhibits inhibitory effects on galactosyl transfer reactions, distinguishing it from its structural isomer D-galactono-1,4-lactone (PMID:3109465 ; PMID:3143309 ). Overall, D-galactono-1,5-lactone plays a significant role in both synthetic organic chemistry and metabolic pathways.
