Ketone bodies are two molecules, acetoacetate and b-hydroxybutyrate. The term. âketone bodyâ is historical: only acetoacetate is an actual ketone. Ketone bodies are. synthesized in the liver from acetyl-CoA. The brain is an important organ. It is metabolically active and metabolically. privileged. The brain generally uses 60-70% of total body glucose requirements, and. always requires some glucose for normal functioning.
Without trying to be too technical I think you can probably say that this ketone body smell is a consequence of fat metabolism. It depends on the nature of the smell. The smell of ketone bodies is characteristically sweet (somewhat like the smell of nail polish remover). It is different from an ammonia- like smell that might result from muscle (protein) breakdown. Ketone bodies are synthesized by the liver whenever fatty acid levels are high in the blood.
