L-Arabinose
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 thearaoperon inE. colithat encodes L-arabinose catabolizing enzymes. It does this by binding to the AraC protein and activating the PBADpromoter. The PBADpromoter 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.Product SpecificationsL-Arabinose; L-Ara; MOLECULAR BIOLOGY GRADEFormula: C5H10O5MW: 150.13 g/molMerck Index: 13,765
