lac·tone  (lktn)
n.
An anhydride formed by the removal of a water molecule from the hydroxyl and carboxyl radicals of hydroxy acids.
[lact(o)- + -one.]
lac·tonic (-tnk) adj.
lactone  (lktn)
Any of various organic esters derived from organic acids by removal of water. Lactones are formed when the carboxyl (COOH) group of the acid reacts with a hydroxyl (OH) group in the same acid, releasing water and causing the carbon atom to join to the hydroxyl's remaining oxygen atom, forming a ring. Vitamin C, the antibiotic erythromycin, and many commercially important substances are lactones.
