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.{{Citation needed|date=March 2025|reason=Claim for physical property should be supported by experimental results.}}
Reduction of allose by catalytic hydrogenation produces an obscure sugar alcohol allitol which is rarely used in the chemical industry.{{cite web |last=Reusch |first=William |date=May 5, 2013 |title=Carbohydrates |url= https://www2.chemistry.msu.edu/faculty/reusch/virttxtjml/carbhyd.htm |website=chemistry.msu.edu |location=East Lansing, Michigan |publisher=Michigan State University |access-date=January 21, 2025}}National Center for Biotechnology Information (2025).
