Description

D-Arabitol (or D-Arabinitol) is the reduced alcohol form of Arabinose. Arabitol is a commonly used food supplement, it is comparably sweet to sucrose but the oral flora cannot metabolize Arabitol, and hence protects from caries. Arabitol plays also an important role in energy controlled diets since it is absorbed slowly by the human digestive tract and has a low caloric content. The differential metabolism of the Arabitol D- and L-forms suggested its use in microbiological diagnostics (Bernard, E.M. et al. 1981) and became a routine urine laboratory test: L-Arabitol is metabolized by a variety of different bacteria and fungi utilizing an arabitol dehydrogenase enzyme. Therefore, it serves as a biomarker for, e.g., invasive candidiasis, since an infection results in an elevated urine D-Arabitol/L-Arabitol (DA/LA) ratio. Cymit Quimica offers both isomers in research grade: D-Arabitol (A-8270) and L-Arabitol (A-8280).
