Phospholipase A2 from honey bee venom is widely used in biochemical research to study the structure and function of cell membranes. It plays a crucial role in breaking down phospholipids, making it valuable for investigating lipid signaling pathways and inflammatory responses. In medical research, it is utilized to understand the mechanisms of venom toxicity and to develop potential antivenom therapies. Additionally, this enzyme is employed in the development of drugs targeting inflammatory diseases, as it helps in understanding the release of arachidonic acid, a precursor to various inflammatory mediators. Its application also extends to studying the immune system's response to allergens, given its presence in bee venom.
