Carbon bonds can be cleaved in oxidation and hydrolysis reactions. They can also be cleaved when two substrates form one product or when one substrate forms two products. When the CO2 or H2O is released a double bond will form. Lyases are the enzymes which catalyze these reactions.

An example which illustrates this is the conversion of fructose 1,6-bisphosphate (6 carbon compound) into dihydroxyacetone phosphate and glyceraldehyde-3-phosphate (both 3 carbon compounds)[1].
