Ketone body modulation of ligand-gated ion channels.

Ketogenesis is a metabolic process wherein ketone bodies are produced from the breakdown of fatty acids. In humans, fatty acid catabolism results in the production of acetyl-CoA which can then be used to synthesize three ketone bodies: acetoacetate, acetone, and β-hydroxybutyrate. Ketogenesis occurs at a higher rate in situations of low blood glucose, such as during fasting, heavy alcohol consumption, and in situations of low insulin, as well as in individuals who follow a 'ketogenic diet' consisting of low carbohydrate and high fat intake.
