caffeine is metabolized in the liver by the cytochrome p450 oxidase enzyme system (specifically, the cyp1a2 isozyme) into three metabolic dimethylxanthines: paraxanthine, theobromine and theophylline. paraxanthine increases lipolysis, leading to elevated glycerol and free fatty acid levels in the blood plasma.
