"WebAcetyl CoA is produced by fatty acid oxidation in the liver mitchondria. During glucose starvation, the liver takes up more fatty acid than it needs for its for own metabolism, so is left with an excess of acetyl CoA. If acetyl CoA were somehow shipped out of the liver to be used by other tissues, the liver would soon be depleted of CoA. " - Can acetyl coa be converted to glucose
