Preferred Label : oxo compounds;
IUPAC definition : Compounds containing an oxygen atom, O, doubly bonded to carbon or another element.
The term thus embraces aldehydes, carboxylic acids, ketones, sulfonic acids, amides
and esters. Oxo used as an adjective (and thus separated by a space) modifying another
class of compound, as in oxo carboxylic acids, indicates the presence of an oxo substituent
at any position. To indicate a double-bonded oxygen that is part of a ketonic structure,
the term keto is sometimes used as a prefix, but such use has been abandoned by IUPAC
for naming specific compounds. A traditional use of keto is for indicating oxidation
of CHOH to C O in a parent compound that contains OH groups, such as carbohydrates,
e.g. 3-ketoglucose.;
