Metabolite Identification
Common NameL-rhamnono-1,4-lactone
DescriptionL-rhamnono-1,4-lactone is a lactone, specifically a cyclic ester derived from L-rhamnose, which plays a role in carbohydrate metabolism. Its chemical structure features a five-membered ring formed by the lactonization of the hydroxyl and carboxyl groups of L-rhamnose. In microbial metabolism, L-rhamnono-1,4-lactone is an important intermediate produced during the nonphosphorylative metabolic pathway, where L-rhamnose is oxidized by the enzyme L-rhamnose 1-dehydrogenase (RhaDH), utilizing NAD(P)+ as a cofactor (PMID:33482017 ). This metabolic process is crucial for certain microorganisms, including Escherichia coli, which actively catalyze the conversion of L-rhamnose to L-rhamnono-1,4-lactone (PMID:22481639 ). Additionally, the structural characterization of L-rhamnono-1,4-lactone has been achieved through single-crystal X-ray diffraction, providing insights into its molecular conformation and interactions (PMID:7805059 ). Overall, L-rhamnono-1,4-lactone serves as a significant compound in the biochemical pathways of various microorganisms, linking carbohydrate metabolism to energy production.
