We concluded that to regulate fat burning, the liver needs ‘new’ fat.” New fat is the fat that is consumed in food or is newly made in the liver as glucose is converted to fat by fatty acid synthase, the enzyme missing in the FASKOL mice. To use the glucose/palmitic acid example in the article glucose has a heat of combustion of 670 kCal/mol and palmitic acid has a value of 2400 kCal/mol. The 2 most contradicting ones are glucose and ketones.
