Metabolite Identification
Common NameDehydroascorbic acid
DescriptionDehydroascorbic acid is a member of the vitamin C chemical class, specifically an oxidized form of ascorbic acid. Its chemical structure features a lactone ring and a carbonyl group, distinguishing it from its reduced counterpart, ascorbic acid. In biological pathways, dehydroascorbic acid plays a crucial role in redox reactions, where it can be converted back to ascorbic acid, thus participating in antioxidant defense mechanisms. For instance, during the ripening of fruits, dehydroascorbic acid levels decrease while ascorbic acid levels rise, indicating its involvement in metabolic transitions (PMID:41101132 ). Additionally, it is found in elevated concentrations in certain patient groups, suggesting its potential relevance in metabolic disorders (PMID:41097488 ). The conversion of ascorbic acid to dehydroascorbic acid is facilitated by various enzymatic processes, including the action of alkaline phosphatase and cerium ions (PMID:40974643 ). Moreover, dehydroascorbic acid is implicated in the induction of cancer cell death when high doses of ascorbic acid are administered, highlighting its importance in therapeutic contexts (PMID:40889352 ). Overall, dehydroascorbic acid serves as a pivotal metabolite in both biochemical pathways and clinical applications.
