Whether acetoacetyl CoA is (1) a reactant but not a product, (2) a product but not a reactant, or (3) a reactant in one step and a product in another step in ketogenesis has to be determined. Concept introduction: Ketone bodies are water-soluble molecules which are synthesized from acetyl CoA through the process of ketogenesis. Ketogenesis occurs in the mitochondria of the liver cells. The initial reactants are the molecules of acetyl CoA which are produced by the β-oxidation of fatty acid molecules. Ketogenesis involves 4 reaction steps. The first and second step involves condensation, the third step is chain cleavage, and the fourth step is hydrogenation. The molecules formed at the end of each reaction step have a different carbon chain length.

Answer 1

Question

Definition Definition Organic compounds that have a carbonyl group, C = O, as their functional group. The carbonyl group in ketones is placed somewhere in the middle of the molecular structure, which means, the C=O is attached to two alkyl groups or benzene rings. Just like all other homologous series, the naming of ketones is done using a common suffix “-one”. The general molecular formula is C n H 2n O. Functional group of a ketone
