Lipidomics is a specialised branch of metabolomics that focuses on the comprehensive analysis of lipids within a biological system. As lipids play crucial roles in cell membrane structure, energy storage, and signaling processes, lipidomics aims to profile and quantify the vast diversity of lipid species, often exceeding thousands in number, present in cells, tissues, or biofluids. Using advanced techniques such as mass spectrometry and chromatography, lipidomics provides insights into lipid metabolism and its alterations in various physiological states, diseases, or responses to treatments. This field is vital for understanding conditions like cardiovascular diseases, obesity, diabetes, and neurodegenerative disorders, where lipid dysregulation plays a central role.
