title: Triglyceride turnover: a comparison of simultaneous determinations using the radioglyceride and the lipolytic rate procedures.
abstract: Two different methods of examining triglyceride turnover are described. One measures the clearance of endogenously labeled triglyceride glycerol, the radioglyceride method. The other assesses the hydrolysis of endogenous very low density lipoproteins after a primed infusion of maximal doses of heparin, the lipolytic rate. Both depend on widely different assumptions. A comparison of data obtained by both methods at the same time in single individuals with widely differing triglyceride concentrations revealed them to agree quite closely. This correspondence indirectly suggests the validity of the procedures. The procedures have been applied to show that fat-free high-carbohydrate diets accelerate triglyceride production in some humans.
