Comparison Studies on Complexation of Molybdenum(VI) with Aspartic Acid And Glutamic Acid in Different Dielectric Constants1
Equilibria of the reaction of molybdenum(VI) with L-aspartic acid (Asp) and L- Glutamic acid(Glu) have been studied by spectrophotometric measurements in mixed solvent systems at an ionicstrength of 0.2 mol/dm3 sodium perchlorate, employed (15, 20, 25, 30± 0.1°C) at pH ranges of 3.2to 5.5 with a high ratio of ligand to metal. The stability constants of the complexes and theresulting free energy...

متن کاملLevulinic acid
THE TITLE COMPOUND (SYSTEMATIC NAME 4-oxo-penta-noic acid), C5H8O3, is close to planar (r.m.s. deviation = 0.0762 Å). In the crystal, the mol-ecules inter-act via O-H⋯O hydrogen bonds in which the hy-droxy O atoms act as donors and the ketone O atoms in adjacent mol-ecules as acceptors, forming C(7) chains along [20-1].
متن کاملGlutamic Acid-l-semialdehyde, a Hypothetical Intermediate in the Biosynthesis of 5-Aminolevulinic Acid
W hether glutamate-l-sem ialdehyde (G -l-SA ) or 4,5 dioxovalerate (DOVA) is the intermedi ate between glutamate and A LA in the C-5 tetrapyrrol pathway is still a matter of controversy. Since no data characterizing G -l-SA are available it is not possible either to identify G -l-SA as intermediate or a precursor of ALA. Therefore, attem pts were made to establish a chemical synthesis of this ...
متن کاملPurification studies of tyrosine-alpha-ketoglutaric acid transaminase.
Recent studies in vitro of tyrosine metabolism have revealed the distribution and the r&e of the tyrosine-a-ketoglutaric acid transaminase system (l-8). In certain of these studies the obligatory rBle of this transaminase as a first step in the conversion of tyrosine to homogentisic acid has been indicated (6-S). The present study is concerned with the partial purification of dog liver tyrosine...
