====== Bioactive lipid ====== Bioactive [[lipid]]s are a class of lipids that have specific biological activities and play important roles in various physiological processes, such as cell signaling, inflammation, and cellular homeostasis. Examples of bioactive lipids include eicosanoids (e.g., prostaglandins, leukotrienes), endocannabinoids (e.g., anandamide, 2-arachidonoylglycerol), sphingolipids (e.g., ceramides), and certain phospholipids (e.g., lysophosphatidic acid). These lipids are generated on demand in response to specific stimuli and exert their effects through specific receptors, often leading to changes in cell behavior and function.
