The Uses of L-(-)-ARABITOL

L-Arabitol, a rare sugar alcohol, is being studied as a food additive that reduces fat deposits in the intestines. L-Arabitol is used as an inducer of xylanase expression in Hypocrea jecorina (Trichoderma reesei). L-Arabitol is used to identify, differentiate and characterize L-arabitol dehydrogenase(s).

Definition

ChEBI: The L-enantiomer of arabinitol.

General Description

Pharmaceutical secondary standards for application in quality control provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards.
L-Arabinitol is formed as a by-product of L-arabinose during the xylitol production in corn cob hydrolysates.

Purification Methods

This pentol, which occurs in the urine of pentosuric subjects, is purified by recrystallisation from 90% EtOH or MeOH. It has a higher rotation in the presence of molybdate: [] 20D -130o (c 0.16, acidified molybdate) [Richtmeyer & Hudson J Am Chem Soc 73 2249 1957].
