L-Talose

L-Talose is a novel substrate of ribose-5-phosphate as well as glucose-6-phosphate isomerases that can be converted into L-tagatose. L-Talose is a type of sugar that is found in plants and animals. It is a stereoselective, synthetic carbohydrate with the chemical formula C12H24O11. L-Talose has an anhydrous dextrose equivalent (DE) of 180. L-Talose is synthesized from D-glucal and D-talonol by a recombinant protein. The immobilization process has been shown to be successful for the production of L-talose as it prevents the loss of product due to adsorption on the surface of the reactor. Molecular modeling was used to determine that L-talose binds to carbonyl groups more strongly than other types of molecules. Anhydrous dextrose was shown to be an effective acceptor for L-talose because it reacts with hydroxyl groups at room temperature and pressure conditions. The nmr spectra show that the hydroxyl group interacts with hydrogen bonding and coordinate covalent bonding.
