MetaCyc Compound Class: a ketone

Superclasses: an aldehyde or ketone

Summary:
a ketone is a compound with the structure RC(=O)R', where R and R' can be a variety of atoms and groups of atoms. It features a carbonyl group (C=O) bonded to two other carbon atoms.

Ketones differ from aldehydes in that the carbonyl is placed between two carbons rather than at the end of a carbon skeleton.

Reactions known to produce the compound:

cuticular wax biosynthesis :
a secondary alcohol + an oxidized unknown electron acceptor → a ketone + an reduced unknown electron acceptor

Not in pathways:
a secondary alcohol + oxygen → a ketone + hydrogen peroxide

Not in pathways:
a nitroalkane + oxygen + H2O → an aldehyde or ketone + nitrite + hydrogen peroxide + H+

In Reactions of unknown directionality:

Not in pathways:
a secondary alcohol + NAD+ = a ketone + NADH + H+
a secondary alcohol + NADP+ = a ketone + NADPH + H+
a secondary alcohol + an oxidized coenzyme F420 = a ketone + a reduced coenzyme F420
a ketone + NADP+ = an enone + NADPH + H+
