| L-(-)-ARABITOL Usage And Synthesis |
| Chemical Properties | white amorphous powder | | Uses | 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). | | Uses | L-Arabitol, a rare sugar alcohol, is being studied as a food additive that reduces fat deposits in the intestines.

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].
