Meaning and Definition
A six-carbon monosaccharide sugar containing a ketone functional group.
A hexose sugar (C₆H₁₂O₆) where the carbonyl group is at position 2, making it a ketone. Important examples in biochemistry include fructose, tagatose, and psicose. They are a subclass of ketoses and are fundamental components of carbohydrate metabolism.

FAQ
Frequently Asked Questions
D-fructose is by far the most common and biologically important ketohexose.
Only indirectly. The prefix 'keto-' refers to ketone chemistry. The ketogenic diet is named for inducing ketosis (production of ketone bodies), not for consuming ketohexose sugars.
Both are 6-carbon sugars. A ketohexose has its carbonyl group (C=O) as a ketone, typically on carbon 2. An aldohexose has its carbonyl group as an aldehyde on carbon 1.
Fructose is a ketohexose found abundantly in honey, fruits, and high-fructose corn syrup, a common sweetener.
A six-carbon monosaccharide sugar containing a ketone functional group.
Ketohexose is usually technical/scientific in register.
Ketohexose: in British English it is pronounced /ˌkiːtəʊˈhɛksəʊz/, and in American English it is pronounced /ˌkiːtoʊˈhɛksoʊs/. Tap the audio buttons above to hear it.
Learning
Memory Aids
Mnemonic
Think: 'KETOne group on a HEX (six) carbon sugar = KETOHEXOSE'. Fructose, the sweet sugar in fruit, is a key example.
Conceptual Metaphor
Often framed as a 'building block' or 'monomer unit' within the larger structure of carbohydrate chemistry and metabolism.
