Bioactive lipids are naturally occurring molecules found in living organisms that play crucial roles in various biological processes. They can influence cell signaling, inflammation, and immune responses. Examples of bioactive lipids include prostaglandins, leukotrienes, and endocannabinoids, which are involved in regulating physiological functions. These lipids can be derived from dietary sources or synthesized within the body. They are important for maintaining health and can impact conditions such as cardiovascular disease and metabolic disorders. Research into bioactive lipids continues to reveal their potential therapeutic applications in medicine and nutrition.
