The seven effects of ketone bodies making them powerful neuroprotectors
There are seven traits allowing ketones to serve as neuroprotectors during brain damage:
- they require only three steps to enter the Krebs cycle (footnote a) – compare with 9 steps obligatory for glucose;
- they cause inhibition of glycolysis, thus decreasing free radical formation;
- they increase production of ATP (footnote b);
- they increase mitochondrial energy efficiency;
- they increase antioxidant activity of glutathione peroxidase (footnote c);
- they spare pyruvate from processing in the Krebs cycle

Footnotesa) The Krebs cycle or the citric acid cycle is a metabolic pathway involved in the conversion (“burning”) of carbohydrates, fats and proteins into CO2 and H2O to generate energy in the form that can be used by living organisms.b) ATP: Adenosine Triphosphate, the ultimate “energy molecule”.c) Glutathione peroxidase: a powerful scavenger of free radicals.
