Altroseis analdohexosesugar.D-Altrose is an unnaturalmonosaccharide.It is soluble in water and practically insoluble inmethanol.However, L-altrose has been isolated from strains of the bacteriumButyrivibrio fibrisolvens.[1]
Altrose is a C-3epimerofmannose.The ringconformationof α-altropyranoside is flexible compared to most other aldohexopyranosides, withidoseas exception. In solution different derivatives of altrose have been shown to occupy both4C1,OS2and1C4-conformations.[2]
