1,5-a-L-Arabinohexaose

1,5-α-L-Arabinohexaose is a carbohydrate. It is a nonreducing sugar that can be found in plants. 1,5-α-L-Arabinohexaose has an optimum pH of 5 and an ethanol concentration of 0.02%. The enzyme form of 1,5-α-L-Arabinohexaose is α-(1→6)-glycosidase. This enzyme hydrolyzes the α-(1→6) glycosidic bond between two glucose residues in a polysaccharide chain to produce β-(1→4) bonds. It also hydrolyzes the β-(1→4) glycosidic bond between two galactose residues to produce β-(1→2) bonds and oxidizes the terminal carbon atom to produce aldehyde products. A structural analysis of this carbohydrate was conducted using marine microorganisms and it was found that they contain galacturonic acid and sugar residues.
