PAF C-18:1 is widely used in biochemical research to study cell signaling pathways, particularly those involving platelet activation and inflammation. It serves as a key molecule in investigating the role of platelet-activating factors in immune responses and vascular biology. Researchers utilize it to understand its effects on cellular receptors and its involvement in conditions like asthma, allergic reactions, and cardiovascular diseases. Additionally, it is employed in the development of therapeutic agents targeting inflammatory disorders. Its application extends to lipidomics studies, where it helps in analyzing lipid metabolism and its impact on cellular functions.
