Summary: This open-access article investigates the gas-phase structures of caffeine and several isomeric caffeine metabolites using cryogenic gas-phase infrared spectroscopy supported by density functional theory. The study demonstrates how protomerism and tautomerism influence molecular identification and shows that gas-phase infrared spectroscopy can distinguish structurally similar metabolites relevant to mass spectrometry-based metabolomics.

Summary: This open-access article shows how electrospray ionisation mass spectrometry can detect protein folding and assembly states during urea-induced denaturation. The study demonstrates that mass spectrometry can resolve folding intermediates that are difficult to capture with conventional ensemble-averaged optical spectroscopy, supporting a more detailed understanding of protein stability and conformational change.
