 Title    Gewinnung trägerfreier Syntheseprodukte in bestrahltem Valin durch heiße 11C-Atome aus (y, n)-Kernreaktionen Carrierfree Synthesis Products from Irradiated Valine by Means of Hot nC-Atoms of Giant Resonance Reaction  
 Abstract    The hot uC-atom derived from (y, n)-nuclear reaction of the 40 MeV-Bremsstrahlung of a electron linear accelerator may react with valine irradiated. Besides retention-labelling of valine new products which are essentially carrierfree may be produced. By this means leucine has been separated using HPLC and identified by electrophoresis in amounts of 25 MBq labelled com­ pound.

 Title    Die Kristallstruktur des Ectoin, einer neuen osmoregulatorisch wirksamen Aminosäure The Crystal Structure of Ectoine, a Novel Amino Acid of Potential Osmoregulatory Function  
 Abstract    The crystal structure of ectoine (l,4,5,6-tetrahydro-2-methyl-4-pyrimidine carboxylic acid) iso­ lated from the extremely halophilic phototrophic bacterium Ectothiorhodospira halochloris was determined by X-ray analysis. This novel cyclic amino acid forms zwitterionic molecules with delocalized ^-bonding in the N-C-N group of the hydrated pyrimidine ring. The molecules are connected by N -H ...O hydrogen bonds. The excellent solubility of ectoine in water can be explained by its structural features which also account for its function as a compatible solute in halophilic bacteria.
