Ethyl arachidonate is primarily used in research and development, particularly in the study of lipid metabolism and inflammatory processes. It serves as a substrate for enzymes like lipoxygenases and cyclooxygenases, which are involved in the biosynthesis of eicosanoids, key signaling molecules in inflammation and immunity. In nutritional science, it is explored for its potential role in brain health and cognitive function, as arachidonic acid derivatives are essential components of neural membranes. Additionally, it is utilized in the formulation of specialized dietary supplements aimed at supporting cellular health and metabolic functions.
