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. Shifting of

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.

Predicting protein decomposition: the case of aspartic-acid racemization kinetics [PDF]

, 1999
The increase in proportion of the non-biological (D-) isomer of aspartic acid (Asp) relative to the L- isomer has been widely used in archaeology and geochemistry as a tool for dating. The method has proved controversial, particularly when used for bones.

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.

Addition of weak acids in electrolytes to prevent osmosis in aqueous organic redox flow batteries

Electrochemistry Communications, 2021
Water transfer issues related to unbalanced ionic strengths in aqueous organic redox flow batteries (AORFBs) are often overlooked. In this work, a simple strategy based on the addition of a weak acid in the negolyte was studied to prevent osmosis in ...

Mutation of aspartic acid 262 on estrogen receptor abrogates estradiol signaling pathway

Gynecological Endocrinology, 2023
Objective ERα (estrogen receptor alpha) exerts nuclear genomic actions and membrane-initiated non-genomic effects. The mutation of aspartic acid into alanine in vitro revealed the critical role of aspartic acid 258 (corresponding to mouse amino acid site

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.
