Molecular Design Strategies for High‐Voltage Organic Cathodes

Advanced Energy Materials, EarlyView.
This work proposes molecular engineering strategies for high‐voltage organic cathode materials for Li‐ion batteries: (1) increase Li‐O coordination number (CN), (2) achieve a greater increase in aromaticity upon reduction (∆Aromaticity), and (3) add an electron‐withdrawing group (EWG), through a combined experimental and computational study on reported

Donor–Acceptor Covalent Organic Framework Enables Ambipolar Charge Storage in Aluminum‐Ion Energy Storage

Advanced Energy Materials, EarlyView.
A donor–acceptor covalent organic framework is designed as an ambipolar cathode for aluminum‐ion energy storage. The crystalline, microporous architecture enables intrinsic charge transport without conductive additives. Multi‐electron redox activity at donor and acceptor sites supports high capacity, excellent stability, and efficient reversible ...

AS‐pHopt: An Optimal pH Prediction Model Enhanced by Active Site of Enzymes

Advanced Intelligent Discovery, EarlyView.
To address the low accuracy of enzyme optimal pH (pHopt) prediction, this study develops active site‐based pHopt (AS‐pHopt), a prediction model enhanced by active site information and pseudo‐label prediction. Integrating key structural and physicochemical features affecting enzyme pHopt, AS‐pHopt uses Evolutionary Scale Modeling (ESM)‐2 with active ...

Generative and Experimental Validation of High Refractive Index Polymers via Domain Knowledge Approach with Small Data

Advanced Intelligent Discovery, EarlyView.
This research demonstrates that the combination of domain knowledge–based multiple regression, multi‐objective Bayesian optimization, and generative models is a suitable prediction tool for candidates of high refractive index polymers, even with the constraints in the model trained on limited data. The experimental validation can reproduce the proposed

Affinity of aromatic amino acid side chains in amino acid solvents

Biophysical Chemistry, 2022
The affinity between amino acid and water is important for understanding how proteins behave in aqueous solutions. For example, the hydrophobicity of amino acid side chains determines a protein's solubility. However, the affinity of amino acid side chains in amino acid solvents should be determined in order to understand the propensity of protein ...

Biosynthesis of the Aromatic Amino Acids

EcoSal Plus, 2008
This chapter describes in detail the genes and proteins of Escherichia coli involved in the biosynthesis and transport of the three aromatic amino acids tyrosine, phenylalanine, and tryptophan. It provides a historical perspective on the elaboration of the various reactions of the common pathway converting erythrose-

Modification of hyaluronic acid with aromatic amino acids

Russian Journal of Bioorganic Chemistry, 2005
Hyaluronic acid was modified with aromatic amino acids (5-aminosalicylic, 4-aminosalicylic, anthranilic, and p-aminobenzoic) in the presence of 1-ethyl-3-[3-(dimethylamino)propyl]carbodiimide. The modified glycans contained 9-43% of arylamide groups and 10-33% of isoureidocarbonyl groups depending on the nature of the amino acid.

Aromatic Amino Acids and Modification of Parkinsonism

New England Journal of Medicine, 1967
THE known biochemical abnormalities in Parkinson's disease consist of a decrease of melanin pigment in the substantia nigra1 , 2 and a decrease of some biogenic amines in the substantia nigra and the corpus striatum.3 These 2 defects might be interrelated, as suggested by the fact that in both melanocytes4 and sympathetic cells5 tyrosine is ...

Aromatic amino acid catabolism in trypanosomatids

Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology, 2008
Trypanosomatids cause important human diseases, like sleeping sickness, Chagas disease, and the leishmaniases. Unlike in the mammalian host, the metabolism of aromatic amino acids is a very simple pathway in these parasites. Trypanosoma brucei and Trypanosoma cruzi transaminate the three aromatic amino acids, the resulting 2-oxo acids being reduced to ...

Differences in properties between aromatic amino acid: Aromatic keto acid aminotransferases and aromatic amino acid: α-ketoglutarate aminotransferases

Life Sciences, 1984
Homogenates of rat liver transaminate phenylpyruvate (PP), as well as alpha-ketoglutarate (alpha-KG), in the presence of L-tyrosine, 3,4-dihydroxyphenylalanine (L-DOPA) or L-tryptophan. Aminotransferase activity with phenylpyruvate and DOPA, but not with tyrosine, was inhibited by excess phenylpyruvate.
