Linoleic Acid Metabolism Service

Online Inquiry

Linoleic acid is a polyunsaturated omega-6 fatty acid. As the two families of essential fatty acids, animals must ingest linoleic acid from diet because the body requires them but cannot synthesize them by themselves. In the body linoleic acid is a metabolic precursor to some long-chain polyunsaturated fatty acids via desaturation and elongation, which happen in the endoplasmic except for the final step which requires translocation to peroxisomes for partial beta-oxidation. Because of this, linoleic acid metabolism can provide many kinds of polyunsaturated fatty acids, which is necessary for good health. Therefore, aberrant linoleic acid metabolism in the procedure of desaturation and elongation lead to various diseases in animals. Scientists at Creative Proteomics utilize a highly quantitative method with LC-MS for the determination of Linoleic Acid levels in various samples.

The detection of linoleic acid and its metabolites can be used to study the metabolic and biological effects of this essential fatty acid in health and disease. Creative Proteomics offers a variety of services to support the analysis of linoleic acid metabolism, including sample preparation, LC-MS analysis, and data analysis.

One of the primary methods used for linoleic acid metabolism analysis is liquid chromatography-mass spectrometry (LC-MS). This technique allows the separation and detection of linoleic acid and its metabolites in biological samples such as plasma, urine and tissues. Creative Proteomics offers LC-MS analysis services for linoleic acid metabolic analysis, which involves the extraction and purification of linoleic acid and its metabolites from samples, followed by separation and detection by LC-MS.

Several assay strategies are available for linoleic acid metabolism analysis, including targeted and non-targeted methods. Targeted assays involve the detection and quantification of specific linoleic acid metabolites, while non-targeted assays involve the detection of all metabolites present in the sample. Both methods have their advantages, and the choice of method depends on the research question and the available resources.

Applications of Linoleic Acid Metabolism Service
