描述
D-allopyranose, also known as hexose, is a member of the class of compounds known as hexoses. Hexoses are monosaccharides in which the sugar unit is a is a six-carbon containing moeity. D-allopyranose is soluble (in water) and a very weakly acidic compound (based on its pKa). D-allopyranose can be found in a number of food items such as ketchup, salt, norway lobster, and american pokeweed, which makes D-allopyranose a potential biomarker for the consumption of these food products. D-allopyranose exists in all living organisms, ranging from bacteria to humans. D-allopyranose 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 .
