Production Ketone bodies are produced mainly in the mitochondria of liver cells, synthesis can occur in response to unavailability of blood glucose. This is caused by low blood glucose levels in the blood, after exhaustion of cellular carbohydrate stores, such as glycogen or ironically, synthesis of ketones can occur due to excessively high levels of blood glucose that are unable to be stored as glycogen in liver and muscle. The production of ketone bodies is then initiated to make available energy that is stored as fatty acid s. Fatty acids are enzymatically broken down in Beta oxidation oxidation to form acetyl CoA .

The solvent is an alcohol such as methanol or ethanol . Image Luche2.png 400px Luche reduction of enones The selectivity can be explained in terms of HSAB theory carbonyl groups require hard nucleophiles for 1,2 addition. The hardness of the borohydride is increased by replacing hydride groups with alkoxide groups, a reaction catalyzed by the cerium salt by increasing the electrophilicity of the carbonyl group. This is selective for ketones because it is more Lewis basic. In one application a ketone is selectively reduced in presence of an aldehyde . Actually in presence of methanol as solvent, the aldehyde forms methoxy acetal which is inactive in the reducing conditions.
