Conformational, Electrochemical, and Antioxidative Properties of Conjugates of Different Ferrocene Turn-Inducing Scaffolds with Hydrophobic Amino Acids

Inorganics
The incorporation of different ferrocene scaffolds into the peptide sequences induces the formation of hydrogen-bond-based secondary structural elements that are frequently observed in natural peptides and proteins.

SPECTROSCOPIC STUDIES ON THE INCLUSION COMPLEXATION OF VALINE ENANTIOMERS WITH β-CYCLODEXTRIN

Journal of Academia, 2023
Complexes of β-cyclodextrin (β-CD) with amino acid analytes such as valine are an ideal study of molecular recognition since L- and D-forms of valine are differently adsorbed on the chiral surface of the β-CD molecule in the aqueous phase.

Amino acid content and biomass productivity of selected weed species as an indicator of their response to herbicide stress

Acta Agrobotanica, 2013
Biomass reduction and amino acid content in plants of Papaver rhoeas L. and Stellaria media L. were investigated to evaluate response of these species to herbicide stress under various temperature (25/16 and 8/2 oC) and relative humidity (50 and 75 ...

Exploring Valine Metabolism in Astrocytic and Liver Cells: Lesson from Clinical Observation in TBI Patients for Nutritional Intervention

Biomedicines, 2020
The utilization of alternative energy substrates to glucose could be beneficial in traumatic brain injury (TBI). Recent clinical data obtained in TBI patients reported valine, β-hydroxyisobutyrate (ibHB) and 2-ketoisovaleric acid (2-KIV) as three of the ...

Investigating the causal association between branched-chain amino acids and Alzheimer's disease: A bidirectional Mendelian randomized study

Frontiers in Nutrition, 2023
BackgroundThere are many metabolic pathway abnormalities in Alzheimer's disease (AD). Several studies have linked branched-chain amino acid (BCAA) metabolism disorders with AD but have not obtained consistent results.

Rethinking plastic waste: innovations in enzymatic breakdown of oil‐based polyesters and bioplastics

FEBS Open Bio, EarlyView.
Plastic pollution remains a critical environmental challenge, and current mechanical and chemical recycling methods are insufficient to achieve a fully circular economy. This review highlights recent breakthroughs in the enzymatic depolymerization of both oil‐derived polyesters and bioplastics, including high‐throughput protein engineering, de novo ...

Dissociation of Valine Cluster Cations [PDF]

The Journal of Physical Chemistry A, 2020
Independently of the preparation method, for cluster cations of aliphatic amino acids, the protonated form MnH+ is always the dominant species. This is a surprising fact considering that in the gas phase, they dissociate primarily by the loss of 45 Da, i.e., the loss of the carboxylic group. In the present study, we explore the dissociation dynamics of

Antibiofilm activity of a chionodracine‐derived peptide by NMR‐based metabolomics of cell‐free supernatant of Acinetobacter baumannii clinical strains

FEBS Open Bio, EarlyView.
KHS‐Cnd peptide is able to impair biofilm formation and disaggregate mature biofilms in Acinetobacter baumannii clinical isolates. Differences in extracellular metabolites reflect changes in biofilm metabolism due to KHS‐Cnd treatment. Among the differentially represented extracellular metabolites upon KHS‐Cnd treatment, the significantly altered ...
