Definition:A pentahydroxycyclohexanone that is cyclohexanone having five hydroxy groups located at positions 2, 3, 4, 5 and 6 (the (2R,3S,4r,5R,6S)-diastereomer). It is the resulting product of the oxidation of C-5 of myo-inositol catalyzed by a putative myo-inositol dehydrogenase Hyg17.
Synonyms:exact_synonym: (2R,3S,4r,5R,6S)-2,3,4,5,6-pentahydroxycyclohexanone
