Ketonen zoals ß-hydroxyboterzuur, aceton en acetoacetaat zijn intermediaire metabolieten van vetzuuroxidatie. Ze worden gevormd wanneer de toevoer van NEFA de oxidatiecapaciteit van de lever overschrijdt.
Ketone bodies can be used by muscle as an alternative fuel source to glucose, sparing glucose for milk production (Herdt, 2000a). However, ketone production does not result in as much net energy release as does complete oxidation of fatty acids. Additionally, increasing concentrations of ketones are thought to suppress feed intake.
