Lipidomics is a discipline that analyzes and identifies lipid metabolites and their interacting molecules in organisms, tissues or cells to understand the structure and function of lipids, and then reveals the relationship between lipid metabolism and the physiological and pathological processes of cells, organs and even organisms. With the advancement of mass spectrometry, lipidomics has shown a wide range of applications in the identification of lipid biomarkers, diagnosis of diseases, discovery of drug targets and lead compounds, and study of drug mechanisms of action.
Targeted lipidomics is based on high-resolution mass spectrometry and isotope internal standard, and uses PRM (parallel reaction monitoring) targeted analysis technology to specifically acquire the signals of multiple lipid molecules (such as dozens of target lipid molecules) simultaneously to obtain their absolute contents and meet the needs of targeted detection and validation of target lipids.
Lipids are hydrophobic or amphipathic small molecules which include fats, waxes, sterols, fat-soluble vitamins (such as vitamins A, D, E and K), monoglycerides, diglycerides and phospholipids. The crucial role of lipids in biological physiology is evident not only in energy storage and structural components of cellular membranes, but also in signal transduction, membrane trafficking and morphogenesis. It is known that mammalian cells contain 1000-2000 types of lipids, but there are many more than that, and it is conservatively estimated that the major lipid species theoretically contain nearly 200000 lipids. Lipids can be broadly classified into three categories, namely, polar lipids including glycerophospholipids and sphingolipids, and nonpolar lipids including glycerol esters and other lipid metabolites such as fatty acids, which are the precursors of biologically active lipid molecules.
The National Institutes of Health (NIH) classifies lipids into eight specific categories including fattyacids, sphingolipids, glycerolipids, glycerophosph1ipids, sterol lipids, saecharolipids, pregnenolipids, and polyketides.
