17-keto-(7Z,10Z,13Z,15E,19Z)-Docosapentaenoic Acid

17-keto-(7Z,10Z,13Z,15E,19Z)-Docosapentaenoic Acid is an oxidized derivative of docosapentaenoic acid (DPA), a lesser-known but biologically significant omega-3 fatty acid that typically occurs in marine and plant oils. This specific derivative is characterized by the introduction of a keto group at the 17th carbon, alongside five double bonds arranged in a cis and trans configuration across the carbon chain. The modification of standard DPA to include a keto group significantly alters its chemical behavior and interaction with biological systems. In research contexts, this molecule is instrumental in studying the effects of oxidative modifications on fatty acids, particularly in understanding how such changes influence lipid signaling pathways and cellular responses. The keto group can potentially engage in specific reactions with proteins and enzymes, altering the normal metabolic pathways of the unmodified fatty acid. This compound has been utilized in studies focusing on lipid peroxidation, a process that plays a crucial role in cell signaling and the regulation of inflammatory responses. Through these studies, 17-keto-DPA aids in elucidating the mechanisms through which oxidized fatty acids can affect cellular processes, including their impact on membrane dynamics, lipid raft formation, and signaling cascades involved in maintaining cellular homeostasis and response to oxidative stress.
