Lipids are essential metabolites that have many crucial cellular functions and can provide a direct readout of cellular metabolic status. The total lipid content in a cell is called a lipidome. Lipidomics is the study of lipidomes using the principles and techniques of analytical chemistry, and emerged in 2003 as an approach to study the metabolism of the cellular lipidome.The analytical power of, and new developments in, mass spectrometry (MS) have accelerated this emerging discipline.
