The Uses of DL-Arabinose
DL-Arabinose is used in physicochemical studies to measure properties such as dielectric relaxation. It may be used in chiral separation of sugars. DL-Arabinose, is a building block of polysaccharide (CCPa-1) from fungus Coprinus comatus Gray, which has potential application as natural antitumor agent with immunomodulatory activity. Arabinose is also used as a culture medium for certain bacteria.
