1,5-a-L-Arabinotriose

1,5-α-L-Arabinotriose is a sugar that is found in the cell walls of plants. It is a trisaccharide composed of three units of D-glucose and one unit of D-xylose. The linkage between the two sugars is an α1,5 bond. 1,5-α-L-Arabinotriose has been shown to be adsorbed on cellulose acetate and can be used to measure the molecular weight of the adsorbate. This sugar also undergoes optical rotations when it interacts with some dyes such as germanium tetrachloride. 1,5-α-L-Arabinotriose has many uses including: as a solute in chloride ion chromatography; as an absorbent in filtration experiments; and as a parameter for calculating thermodynamics for reactions involving hydrogen transfer.
