WebOne of the two atoms of oxygen from molecular oxygen is incorporated into the oxidatively decarboxylated α-keto acid product (succinic acid, when the α-keto acid is α-ketoglutarate); the other atom of oxygen either goes into the substrate when hydroxylation occurs or into water when a ring cyclization occurs. Sign in to download full-size image Webα-Keto acids and their esters exhibit unique structures that directly connect a keto carbonyl group and a carboxyl group. On the basis of the characteristic structures of α-keto acids, it is inferred that the C–C bonds linking the above-mentioned groups are easily cleaved to release CO 2, and the acidity of the α-proton of the keto carbonyl group and …
WebKetone bodies are the by-product of this process, which consist chemically of three substances, namely β-hydroxybutanoic acid, acetoacetic acid, and acetone. When ketone bodies are released in the body, they enter the bloodstream, acidify the blood, and are eventually excreted, mostly in urine, which exhibits a fruity smell, mainly due to acetone.
