Common NameD-glucaro-1,5-lactone
DescriptionD-glucaro-1,5-lactone is a lactone, specifically a cyclic ester derived from D-glucaric acid. Its chemical structure features a five-membered ring formed by the intramolecular esterification of the carboxylic acid and hydroxyl groups of D-glucaric acid. This compound has been implicated in various biochemical pathways, particularly in the context of glycosaminoglycan metabolism. Notably, D-glucaro-1,5-lactone has been shown to exhibit a high binding affinity to D-glucuronic acid and its substrate intermediates, including D-glucaro-1,4-lactone, as evidenced by studies on Q14F, S36L, and S75T mutants (PMID:31472210 ). Additionally, it has been identified as a potent inhibitor of beta-D-glucuronidase, suggesting its role in modulating glucuronidation processes, which are crucial for the detoxification of various substances in the body (PMID:3779687 ). The lactone's involvement in these pathways highlights its potential significance in metabolic regulation and enzymatic activity related to glucuronidation.
