Isotope dilution techniques can be used in vivo to measure carbohydrate, fatty acid, glycerol and amino acid metabolism. Fatty acid concentration and composition can also be analysed as measures of synthesis or dietary intake.
The synthesis rates of macromoelcules such as apolipoproteins, muscle protein, cholesterol, triacylglycerol and fatty acids (de novo lipogenesis) can be measured in vivo and in vitro. Total energy expenditure can be determined following ingestion of double labelled water. Measurement of labelled CO2 can be used to calculate the oxidation rates of metabolites.
