L-ASPARTIC ACID FORMATION PROM N-ACETYL-L-ASPARTIC ACID IN THE BRAIN

Psychiatry and Clinical Neurosciences, 1961
Summary 1. Radioactive L-aspartic acid was produced by incubating C i*-N-acetyl-L-aspartic acid with a mouse brain homogenate. 2. Glutathione and Co++ must co-exist to activate this reaction. However, the reaction could be performed more or less by using Fe++, Cu++, Ca++, and Zn*+ instead of Co*H. 3.

2-(2-Pyridyl) benzimidazole based Co(II) complex as an efficient fluorescent probe for trace level determination of aspartic and glutamic acid in aqueous solution: a displacement approach.

Organic and biomolecular chemistry, 2011
A weakly fluorescent cobalt(II) complex is synthesized using 2-(2-pyridyl)-benzimidazole (PBI) as a chelating fluorescent ligand and characterized by single crystal X-ray structure.

Decarboxylation of Aspartic and Glutamic Acids

Nature, 1938
ACCORDING to our earlier reports1, the legume bacteria split off quantitatively one of the carboxyl groups from l-aspartic acid forming β-alanine, HO2C.CH2.CH(NH2).CO2H→HO2C.CH2.CH2NH2 + CO2. The reaction was at first accomplished only with living bacteria.

Aspartic-acid synthesis in C3 plants

Planta, 1991
In a previous study (Melzer and O'Leary, 1987, Plant Physiol. 84, 58-60), we used isotopic methods to show that a substantial fraction of protein-bound aspartic acid in tobacco is derived from anaplerotic synthesis via phosphoenolpyruvate (PEP) carboxylase.

生命的起源與天門冬氨酸在水中的結晶; The Origin of Life and the Crystallization of Aspartic Acid in Water

, 2010
The unusual molecular complexation of the enantiomers of aspartic acid in water was discovered and proven by a solubility test, solution freezing point, crystallization kinetics, and the incubation time change.

Solubility of D-Aspartic Acid and L-Aspartic Acid in Aqueous Salt Solutions from (293 to 343) K

, 2010
The solubility of d-aspartic acid and l-aspartic acid in aqueous solutions of various molalities of sodium chloride and potassium chloride was measured by using a laser technique from (293 to 343) K at atmospheric pressure.

Polarography of molybdenum in aspartic acid solution

Talanta, 1968
The polarographic behaviour of Mo(VI) in solutions of aspartic acid is reported. In 0.01M acid, two waves are obtained, but at pH 4 only one, and they are diffusion controlled. The determination is possible in the presence of Ni, Cr(VI), W(VI), Mn(II), Co(II), Cu(II) or Th, with an accuracy of 2% in the range 10(-5)-10(-3)M.

Absorption, utilization, and safety of aspartic acid

Journal of Toxicology and Environmental Health, 1976
The dicarboxylic amino acids, asparate and glutamate, occupy unique positions in intermediary metabolism, particularly in the mitochondria, where they play important roles in nitrogen and energy metabolism. Administration of large quantities of glutamate and asparate to the newborn mouse produces a variety of neurotoxic effects, the most marked of ...

Rate of Aspartic Acid Racemization in Bone

The American Journal of Forensic Medicine and Pathology, 1998
There are no reports on rates of amino acid racemization in bones. To investigate the possibility of estimating age by evaluating amino acid residue racemization in human bones, a heating experiment was performed and the rate of aspartic acid racemization was determined using the Arrhenius equation.
