Originally considered as lipid storage compartments, lipid droplets are currently recognised as organelles with high metabolic activity. The defective formation and/or function of lipid droplets is involved in various pathogenic conditions, such as obesity, cardiovascular diseases, type 2 diabetes, or metabolic syndrome. glycerophospholipid https://goldbook.iupac.org/terms/view/09839 PAC, 2018, 90, 1121.
