Hexuloses
Hexuloses or ketohexoses is the name for ketoses with an unbranched chain of six carbon atoms ( hexoses ). The hexuloses include, for example, sorbose , psicose and tagatose . The keto group is usually located in the C2 position of the molecule as a free or cyclic hemiketal . Hexuloses have up to three asymmetrically substituted carbon atoms, which are often distinguished by the prefixes arabino, ribo-, xylo- or lyxo- derived from the trivial names.
The designation hexulose corresponds to the IUPAC / IUBMB rule 2-Carb-10.3.
