[C][C][Branch1][#Branch1][C][C][=Branch1][C][=O][O-1][O]"}, {"from": "gpt", "value": "The molecule is a hydroxy fatty acid anion and ketone body synthesized in the liver from acetyl-Coenzyme A (acetyl-CoA) by the enzyme 3-hydroxybutyrate dehydrogenase. 3-hydroxybutyrate can be used as an energy source when glucose levels drop. Elevated urine and serum levels of 3-hydroxybutyrate are seen in ketosis and ketoacidosis."}]
