'''Ketoheksoza''' je [[heksoza]] koja sadrži [[keton]]sku grupu (šestougljenični [[monosaharid]]).<ref>{{Cite book|title = The vocabulary of organic chemistry | editor-last = Milton Orchin | editor-first = Milton | publisher = Wiley | year = 1980 |isbn=9780471044918}}</ref> Najzastupljenije ketoheksoze, svaka od kojih je zastupljena sa parom [[enantiomer]]a (<small>-{D}-</small>- i <small>-{L}-</small>-izomera), su [[fruktoza]], [[psikoza]], [[sorboza]], i [[tagatoza]]. Ketoheksoza je stabilna na širokom -{pH}- opsegu. Pošto je primarna -{p''K''<sub>a</sub>}- vrednost 10.28, ona se deprotonuje samo na visokom [[pH вредност|-{pH}-]], tako da je marginalno manje stabilna od [[aldoheksoza|aldoheksoze]] u rastvoru.<ref>{{Cite book |title=Essentials of Carbohydrate Chemistry and Biochemistry |last= Lindhorst|first=Thisbe K.|publisher=Wiley-VCH | edition = 1. |year=2007 |isbn=978-3-527-31528-4}}</ref><ref>{{Cite book |title=Essentials of Carbohydrate Chemistry |publisher=Springer |last= Robyt|first=John F.| edition = 1. |year=1997 |isbn=978-0-387-94951-2}}</ref>
