Product Application of DL-ArabinoseCAS#147-81-9
DL-Arabinose is applied in physicochemical research to determine characteristics like dielectric relaxation. It can also be utilized for the chiral resolution of sugar compounds. As a structural component of the polysaccharide CCPa-1 derived from the fungus Coprinus comatus Gray, it shows promise as a natural antitumor agent with immunoregulatory functions. In addition, arabinose serves as a component in culture media for specific bacterial strains.
