Allose is an aldohexose sugar. It is a rare monosaccharide that occurs as a 6-O-cinnamyl glycoside in the leaves of the African shrub Protea rubropilosa. Extracts from the fresh-water alga Ochromas malhamensis contain this sugar but of unknown absolute configuration. It is soluble in water and practically insoluble in methanol.
Reduction of allose by catalytic hydrogenation produces an obscure sugar alcohol allitol which is rarely used in the chemical industry.National Center for Biotechnology Information (2025). PubChem Compound Summary for CID 120700, Allitol. Retrieved January 21, 2025 from Allitol.
