Detection of L-Aspartic Acid with Ag-Doped ZnO Nanosheets Using Differential Pulse Voltammetry

Biosensors, 2022
Here, a sensitive voltametric electrochemical sensor probe was fabricated to reliably trace the detection of L-aspartic acid in phosphate-buffered medium using a glassy carbon electrode (GCE) layered with a film of wet-chemically prepared Ag2O-doped ZnO ...

Designing and In Vitro Characterization of pH-Sensitive Aspartic Acid-Graft-Poly(Acrylic Acid) Hydrogels as Controlled Drug Carriers

Gels, 2022
Acetaminophen is an odorless and white crystalline powder drug, used in the management of fever, pain, and headache. The half-life of acetaminophen is very short; thus, multiple intakes of acetaminophen are needed in a day to maintain a constant ...

The role of aspartic acid in reducing coral calcification under ocean acidification conditions [PDF]

, 2020
Biomolecules play key roles in regulating the precipitation of CaCO3 biominerals but their response to ocean acidification is poorly understood. We analysed the skeletal intracrystalline amino acids of massive, tropical Porites spp.

A neutron laue diffraction study of endothiapepsin: Implications for the aspartic proteinase mechanism [PDF]

, 2001
Current proposals for the catalytic mechanism of aspartic proteinases are largely based on X-ray structures of bound oligopeptide inhibitors possessing nonhydrolyzable analogues of the scissile peptide bond.

Specific Adsorption of Aspartic Acid on Iron (III) and Nickel (II) Oxides

Eurasian Chemico-Technological Journal, 2012
The dependences of zeta - potential and adsorption of aspartic acid on NiO and Fe2O3 oxideswere investigated as a function of aspartic acid concentration, pH and adsorption time using microelectrophoresis and potentiometric titration methods.

Restoring the biological activity of crizanlizumab at physiological conditions through a pH-dependent aspartic acid isomerization reaction

mAbs, 2023
In this study, we report the isomerization of an aspartic acid residue in the complementarity-determining region (CDR) of crizanlizumab as a major degradation pathway.

The aspartic proteinase family of three Phytophthora species [PDF]

, 2011
Background - Phytophthora species are oomycete plant pathogens with such major social and economic impact that genome sequences have been determined for Phytophthora infestans, P. sojae and P. ramorum.

Sensitive and Rapid Detection of Aspartic Acid with Co₃O₄-ZnO Nanorods Using Differential Pulse Voltammetry

Biosensors, 2023
Herein, the detection of aspartic acid by doped Co3O4-ZnO nanorod materials was proposed using differential pulse voltammetry. The nano-composite metal oxide was synthesized by the wet precipitation method in basic media. Aspartic acid is a non-essential

Isolation and functional verification of an aspartate aminotransferase gene from Neoporphyra haitanensis

BMC Plant Biology, 2023
Background Neoporphyra haitanensis is a commercial laver species in China. Aspartic acid is an important flavor amino acid, and aspartate aminotransferase (AAT) is a crucial enzyme in its biosynthesis.

Strecker degradation products of aspartic and glutamic acids and their amides

Czech Journal of Food Sciences, 2001
Aspartic and glutamic acids, asparagine and glutamine were oxidised with either potassium peroxodisulphate or glyoxal. Nonvolatile products were derivatised and analysed by GC/FID and GC/MS.
