Lipoxygenase is an enzyme that plays a crucial role in the metabolism of fatty acids, particularly in the conversion of arachidonic acid into various lipid mediators. These mediators are important for several biological processes, including inflammation and cell signaling. Lipoxygenase is found in many tissues, including the lungs and platelets. This enzyme is involved in the production of leukotrienes, which are signaling molecules that can influence immune responses and allergic reactions. Dysregulation of lipoxygenase activity has been linked to various diseases, such as asthma and cardiovascular disorders, making it a target for therapeutic interventions.
