Allose

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.
Allose is a C-3 epimer of glucose.
