Abstract Molecular networking connects mass spectra of molecules based on the similarity their fragmentation patterns. However, during ionization, commonly form multiple ion species with different behavior. As a result, these often remain unconnected in tandem spectrometry-based molecular networks, leading to redundant and disconnected sub-networks same compound classes. To overcome this bottleneck, we develop Ion Identity Networking (IIMN) that integrates chromatographic peak shape...
Herein, we present a protocol for the use of Global Natural Products Social (GNPS) Molecular Networking, an interactive online chemistry-focused mass spectrometry data curation and analysis infrastructure. The goal GNPS is to provide as much chemical insight untargeted tandem set possible connect this underlying biological questions user wishers address. This can be performed within one experiment or at repository scale. not only serves public with sample information (metadata), it also...
Abstract Molecular networking connects tandem mass spectra of molecules based on the similarity their fragmentation patterns. However, during ionization, commonly form multiple ion species with different behavior. To connect same molecule, we developed Ion Identity Networking. These new relationships improve network connectivity, are shown to reveal novel ion-ligand complexes, enhance annotation within molecular networks, and facilitate expansion spectral libraries.
AimThiss study was conducted to investigate the possible role of a compatible solute from radio‐halophilic bacterium against desiccation and ultra‐violet radiation‐induced oxidative stress.
