Extra Details:: L(+)-Arabinose is a pentose monosaccharide whose transcription is regulated by Ara-C proteins and is a substrate for L-arabinose dehydrogenase, galactose dehydrogenase. It is not fermented by yeast. Used as a one-way or reversible switch for protein expression. It is also used to make arabinosyl nucleosides. L-Arabinose is used as a substrate to identify, differentiate and characterize pentose sugar isomerase(s). L-Arabinose is used in the bioproduction of L-ribose. L-Arabinose is the naturally occurring isomer and is a constituent of plant polysaccharides. Most bacteria contain an inducible arabinose operon that codes for a series of enzymes and transporters that allows L-arabinose to be used as the sole carbon source in microbial culture.
