Oxovanadium(iv) complexes of salicyl-l-aspartic acid and salicylglycyl-l-aspartic acid
Dalton Transactions, 2005The dipeptide and tripeptide analogues salicyl-L-aspartic acid (Sal-L-Asp) and salicylglycyl-L-aspartic acid (SalGly-L-Asp) were synthesized and their protonation and complex formation with V(IV)O2+ were studied in aqueous solution through the use of pH-potentiometry and spectroscopic (UV-Vis, CD and EPR) techniques. The phenolate terminus proved to be

Speciation of iron(III) (cFe = (0.5 - 40)x10^-5 mol dm-3) and indirectly of iron(II), in aqueous solution of L-aspartic acid and aspartic acid - glycine mixture was investigated by square-wave voltammetry on a static mercury drop electrode. A reversible, one-electron reduction process of iron(III)- aspartate complexes with peak potential between +0.04 ...

Aspartase (L-aspartate ammonia lyase, EC 4.3.1.1) catalyses the reversible amination and deamination of L-aspartic acid to fumaric acid which can be used to produce important biochemical. In this study, we have explored the characteristics of aspartase from Pseudomonas aeruginosa PAO1 (PA-AspA).

L-ASPARTIC ACID FORMATION PROM N-ACETYL-L-ASPARTIC ACID IN THE BRAIN
Psychiatry and Clinical Neurosciences, 1961Summary 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.

Synthesis of Deuterium Derivatives of L-Aspartic Acid
The Journal of Biochemistry, 1962All the possibie deuterium derivatives of L-aspartic acid were prepared by combining various enzymic and chemical reactions. Deuterium analysis by mass spectrometry showed the syntheses proceeded as expected. A comparison of the infrared absorption spectra of the 16 preparations showed they were all different and not contaminated with each other ...

Mutagenicity studies with N-acetyl-l-aspartic acid
Food and Chemical Toxicology, 2009Analytical studies have reported that N-acetyl-L-aspartic acid (NAA) is present at low concentrations in many foods. The current studies were conducted to assess the mutagenicity of NAA using standard OECD guideline in vitro bacterial and in vivo mammalian mutagenicity studies.

Abstract Reaction of L-aspartic acid with excess of bis(trimethylsilyl)amine under reflux provides optically pure L-aspartic acid bis(trimethylsilyl) ester in quantitative yield. This silyl ester reacts with a variety of acylating reagens in tetrahydrofuran to give N-protected aspartic acids and dipeptides in good yields without racemization.

On the solvation of L-aspartic acid
Molecular Physics, 2004We use molecular statics and dynamics to study the stability of L-aspartic acid both in vacuo and solvated by polar and non-polar molecules using density functional theory in the generalized gradient approximation. We find that structures stable in vacuo are unstable in aqueous solution and vice versa.

Active transport of l-aspartic acid in Neurospora crassa
Biochimica et Biophysica Acta (BBA) - Biomembranes, 1971Abstract Transport of l -aspartic acid in Neurospora crassa conidia is shown to be mediated by neutral and general amino acid transport systems. The transport activity is dependent on pH and results in accumulation of l -aspartic acid against a gradient. Mutants deficient in transport of l -aspartic acid are described.
