When Two Dimensions Matter: A Critical Review of Recent Comprehensive Two‐Dimensional Gas Chromatography Applications in Food Analysis

ChemFoodChem, EarlyView.
Comprehensive two‐dimensional gas chromatography (GC×GC) is gaining importance in food analysis, particularly for volatile and aroma‐related compounds. This review examines recent applications across plant‐, animal‐, and other food matrices, revealing trends in sample preparation, column selection, modulation and detection, while highlighting ...

Influence of Head‐to‐Tail Cyclization of Lanmodulin‐Inspired Peptides on Lanthanide Affinity and Structure

Chemistry – A European Journal, EarlyView.
The influence of head‐to‐tail cyclization, as well as the effect of ring expansion with an additional glycine on lanmodulin‐inspired peptides on the structure and lanthanide (Ln)‐binding behavior was investigated. While the decrease of structural flexibility can indeed increase the Ln affinity and peptide pre‐organization, it does not lead to an ...

Tailoring Liquid Crystalline Self‐Assembly and Photophysical Properties of Unsymmetrical Fluorenones via Polar Terminal Groups

Chemistry – A European Journal, EarlyView.
Novel liquid crystalline fluorenones bearing various head groups were synthesized and characterized. By alteration of the head group, N, SmC, or SmA phases were obtained, and emission properties could be tuned depending on solvent or temperature. ABSTRACT In this work, a series of novel unsymmetrical fluorenone derivatives bearing various head groups ...

Reversible Cystine Disulfide Scaffolding Enables Carbonyl Sulfide‐Mediated Intramolecular Peptide Bond Formation via Cyclocystine: Implications for Prebiotic Chemistry

Chemistry – A European Journal, EarlyView.
Cystine is unique among amino acids, in that the disulfide bond can allow intramolecular peptide bond formation. This cyclization offers potential advantages for intramolecular coupling selectivity in prebiotic peptide formation. ABSTRACT Treatment of cystine (the disulfide‐linked dimer of cysteine) with carbonyl sulfide (COS) results in the formation ...
