Lipid composition research focuses on the study of the types and ratios of different lipids present in cellular membranes, tissues, or biological fluids. Lipids are a diverse group of molecules including fats, oils, phospholipids, and cholesterol that play essential roles in cell structure and function. Understanding the lipid composition of cells and tissues can provide insight into various physiological processes and diseases. Techniques such as lipidomics and mass spectrometry are commonly used to analyze and quantify lipid species in biological samples. Studying lipid composition can help uncover biomarkers for disease diagnosis, identify potential drug targets, and improve our understanding of lipid metabolism and signaling pathways.
