al·dol con·den·sa·tion

formation of an aldol (a β-hydroxy carbonyl compound) from two carbonyl compounds; the reverse reaction is an aldol cleavage; fructose 1,6-bisphosphate aldolase catalyzes such a reaction.


(ăl′dôl, -dōl)
1. A thick, colorless to pale yellow liquid obtained from acetaldehyde and used in perfumery and as a solvent.
2. A similar aldehyde containing the group CH3OH-CO-CHOH.
