CétoacideLes cétoacides sont des acides organiques portant une fonction acide carboxylique et une fonction cétone. On divise cette famille en sous-familles, en classant les composés par rapport aux positions respectives des deux fonctions. On compte parmi ces sous-familles: les alpha-cétoacides, ou 2-oxoacides, qui comme l'acide pyruvique ou le 2-oxoglutarate ou le 2-oxoisovalérate, ont leur fonction cétone adjacente à leur groupe carboxyle (sur le carbone α).
DicarbonylIn organic chemistry, a dicarbonyl is a molecule containing two carbonyl () groups. Although this term could refer to any organic compound containing two carbonyl groups, it is used more specifically to describe molecules in which both carbonyls are in close enough proximity that their reactivity is changed, such as 1,2-, 1,3-, and 1,4-dicarbonyls. Their properties often differ from those of monocarbonyls, and so they are usually considered functional groups of their own.
