What’s L-Arabinose powder?
L-Arabinose is an arabinose isomer widely found in nature, while D-arabinose is less common. L-Arabinose 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.
L-Arabinose is a white crystalline powder, no odour, freely soluble in water, slightly soluble in alcohol, and not soluble in ether, methanol and acetone. It is also known as pectinose, pectin sugar, and gum sugar, and is a kind of aldopentose. L-Arabinose rarely exists in nature in the form of monosaccharide, usually combining with other monosaccharides, existing in pectin, hemicellulose, pectin acid, polysaccharide of bacteria and some glycoside in the form of heteropolysaccharide. It is high stable against acid and heat.
