On the solvation of L-aspartic acid

Molecular Physics, 2004
We 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.

Bioproduction of l-Aspartic Acid and Cinnamic Acid by l-Aspartate Ammonia Lyase from Pseudomonas aeruginosa PAO1

Applied Biochemistry and Biotechnology, 2017
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).

Speciation of biochemically important iron complexes with amino acids: L-aspartic acid and L-aspartic acid - glycine mixture

Electrochimica Acta, 2014
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 ...

Mutagenicity studies with N-acetyl-l-aspartic acid

Food and Chemical Toxicology, 2009
Analytical 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.

Antinociceptive effect of d-Aspartic acid in mice

Pharmacology Biochemistry and Behavior, 1995
The effects of D- and L-aspartic acids on the nociceptive tail flick reflex in mice were investigated. D-Aspartic acid (115-230 mg/kg, IF) was found to increase tail flick latency significantly.

Recent advances in the metabolic engineering and physiological opportunities for microbial synthesis of L-aspartic acid family amino acids: A review.

International Journal of Biological Macromolecules, 2023
L-aspartic acid, L-threonine, L-isoleucine, l-lysine, and L-methionine constitute the l-aspartate amino acids (AFAAs). Except for L-aspartic acid, these are essential amino acids that cannot be synthesized by humans or animals themselves. E.

Sustainable synthesis of carbon dots from agarose waste and prospective application in sensing of l-aspartic acid

Materials research bulletin, 2021
The excessive utilization of carbon dots (CDs) has led to different fates and perseverance which further prejudiced by various photochemical and other transformations. The mechanistic behaviour of their respective conversions is still very unclear.
