Metabolite Identification
Common NameL-Glucitol
DescriptionL-Glucitol is a sugar alcohol belonging to the class of polyols. Its chemical structure is characterized by a six-carbon chain with hydroxyl groups (-OH) attached to each carbon, making it a hexitol. In biochemical pathways, L-glucitol is primarily involved in the metabolism of certain bacteria, where it can be catabolized to D-sorbose, a process observed in Stenotrophomonas maltophilia (PMID:11823194 ). This conversion occurs during growth on L-glucitol as the sole carbon and energy source, and the enzymes facilitating this pathway have been identified, highlighting their roles in intermediary metabolism (PMID:11823194 ). Additionally, L-glucitol can serve as a substrate for L-glucitol oxidizing dehydrogenase, which catalyzes its oxidation to D-sorbose, demonstrating its potential for industrial applications (PMID:24061413 ). The enzyme exhibits enantioselective activity, converting D-glucitol to D-fructose while also facilitating the regeneration of cofactors (PMID:24061413 ). Furthermore, various derivatives of L-glucitol have shown significant biological activities, including antidiabetic effects and specific inhibition of alpha-L-fucosidase, indicating its relevance in pharmacological research (PMIDs:16719780, 11858756).
