CHEMICAL AND BIOLOGICAL STUDIES WITH DEUTERIUM
A basic flowsheet is presented for the production of deuterium oxide by the H/sub 2/O/H/sub 2/S dual-temperature exchange process. Cost factors are discussed. The physical properties of H/sub 2/O and D/sub 2/O are compared. It is shown that the substitution of hydrogen by deuterium in water gives rise to marked changes in physical properties. Applications of deuterium in chemical and biological studies are reviewed. Topics discussed include kinetic isotope effects of deu terium compounds; reaction rate phenomena which are known to exhibit isotope effects; the deuterium isotope effect in living systems; the growth of algae in heavy water; a comparison of ordinary and deuterated algae; the isolation of deuterated chloroplast pigments and other fully deuterated compounds from algae; photosynthesis in deuterated green algae; deuterium isotope effects on mammals; deuterium isotope effects on tumor growth; and the preparation of compounds in which hydrogen is replaced by deuterium.
