Description
L-Arabinose is an aldopentose – a monosaccharide containing five carbon atoms, and including an aldehyde (CHO) functional group. For biosynthetic reasons, most saccharides are almost always more abundant in nature as the “D”-form, or structurally analogous to D-glyceraldehyde. However, L-arabinose is in fact more common than D-arabinose in nature and is found in nature as a component of biopolymers such as hemicellulose and pectin. The L-arabinose operon is a very important operon in molecular biology and bioengineering. A classic method for the organic synthesis of arabinose from glucose is the Wohl degradation. Arabinose is used as a culture medium for certain bacteria.
L-Arabinose is widely found in nature, while D-arabinose is less common and is a constituent of many biopolymers that make up plant cell walls.
This monosaccharide is often used in cell culture media, serving as a bacterial carbon source, and can be used to distinguish between bacteria based on their fermentation abilities.
L-Arabinose, in the absence of glucose, induces transcription of the ara operon in E. coli that encodes L-arabinose catabolizing enzymes. It does this by binding to the AraC protein and activating the PBAD promoter. The PBAD promoter is used in plasmid vectors as a switch for protein expression that can be turned on by L-arabinose or turned off by addition of glucose.

Applications of L-Arabinose
It can be used as a functional food addictive for alleviating hypertension, hyperglycemia, hyperlipemia. As L-arabinose has fine food compatibility, it can be used in beverage products, candy, baked foods. L-arabinose can help solve “frosting” of chocolate and “sandy” of candy. As a reducing monosaccharide, L-arabinose contains an aldehyde group, which reacts with the amino acids, proteins and other substances (Maillard browning reaction) to form unique flavor and more bright color in the preparation of baked foods.
It can be used as a non-prescription drugs as an anti-obesity nutritional supplements, or as a medicine pharmaceutical excipients and filling agents for syrups and tablets since it is difficult to be absorbed and utilized to generate energy in the body and the non-utilized part can be excreted from the urine.
It can also be used for the synthesis of important pharmaceutical intermediates. Five anti-hepatitis B drugs entered into the Phase three clinical trials globally in 2010-2014, two of which uses L-arabinose as raw material, namely Clevudine (L-FMAU) of the Korean Bukwang Pharmaceuticals and Telbivudine of the United States Idenix Pharmaceuticals. These two drugs able to specifically inhibit the hepatotropic DNA viruses without an impact on the DNA polymerase and mitochondrial function, currently it has been widely used in the clinical treatment of hepatitis B.
It is an ideal synthesis intermediates for flavors: study shown that flavor synthesized from L-arabinose has a soft, rich aroma, which is more natural and plump aroma. An increasing number of foreign flavor companies are trying to use L-arabinose in the production of Synthetic essence.
