Descrizione

Descrizione generale

D-Arabinose is a rare aldopentose, and is rarely utilized by enteric bacteria as a source of carbon and energy. It is also found in the aloins of the plant genus Aloe and as a constituent of the polysaccharide of the bacterial genus Mycobacterium. Some of the enteric bacteria like Escherichia coli K-12 can mutate to utilize D-arabinose.

Applicazioni

D-(-)-Arabinose has been used as an inducer of λ-RED recombinant gene expression.

Azioni biochim/fisiol

D-Arabinose is a reducing sugar. It is a pentose analog of D-ribose that is a constituent of mycobacterial cell wall arabinogalactans. It is also a substrate for D-erythroascorbic acid synthesis in yeast.
