Oxylipidomics Service

    Oxylipids, bioactive molecules derived from the oxidation of unsaturated fatty acids like linolenic, arachidonic, and eicosatetraenoic acids, encompass compounds such as prostaglandins, leukotrienes, and various enols and ketones. Oxylipidomics, a burgeoning field, delves into the composition, distribution, transformation, and function of oxylipids in biological systems. Given their pivotal roles in cellular signaling and disease pathogenesis, understanding the dynamics of oxylipids is crucial for elucidating the mechanisms underlying diseases like inflammation, cardiovascular disorders, immune responses, cancer, and neurodegenerative conditions. Thus, precise analysis and evaluation of these oxylipids are essential for disease prevention, diagnosis, and treatment.

     

    Oxylipidomics primarily involves the identification and quantification of oxylipids. The chemical diversity and dynamic nature of these compounds necessitate the use of sophisticated, highly sensitive mass spectrometry techniques, particularly liquid chromatography-mass spectrometry (LC-MS) and gas chromatography-mass spectrometry (GC-MS). These methods provide comprehensive qualitative and quantitative insights into the types, structures, and concentrations of oxylipids.

    Analysis Workflow

    1. Lipid Extraction

    Lipids are extracted using organic solvents like methanol and chloroform.

     

    2. Chromatographic Separation

    Depending on the properties lipid extraction, separation is conducted by LC or GC.

     

    3. Mass Spectrometry

    Post-separation, lipids are analyzed though electrospray ionization (ESI) and TOF-MS to determine their mass and structural details.

     

    4. Data Analysis

    Lipid is identified and quantified by using specialized software, analyzing mass spectra, and matching with established databases.
