During the last decades several new techniques have been developed for measuring the utilization of nutrients in humans. The development and potential use of techniques with stable isotopes are discussed. Examples of the different studies are presented for determining whole body aminoacid and protein dynamics like lipids and glucose metabolism in humans. The practical use of these diverse stable isotopically labeled biochemicals provide safe, ethical, noninvasive investigation of nutritional metabolism in humans.

D006859	Hydrogen	The first chemical element in the periodic table with atomic symbol H, and atomic number 1. Protium (atomic weight 1) is by far the most common hydrogen isotope. Hydrogen also exists as the stable isotope DEUTERIUM (atomic weight 2) and the radioactive isotope TRITIUM (atomic weight 3). Hydrogen forms into a diatomic molecule at room temperature and appears as a highly flammable colorless and odorless gas.	Protium,Hydrogen-1
