WitrynaThe most important chemical reactions of aldehydes and ketones are: Nucleophilic addition of water; A water (H 2 O) molecule is added across the C=O double bond to yield the corresponding gem-diols. The C=O double bond breaks and 2 OH groups are added onto this carbon atom to form a dihydric alcohol. ... Uses of aldehydes and … WitrynaAbstract. Ketone bodies are produced in the liver and are utilized in other tissues in the body as an energy source when hypoglycemia occurs in the body. There are three ketone bodies: acetoacetate, beta hydroxy butyrate, and acetone. Ketone bodies are usually present in the blood, and their level increases during fasting and starvation.
