1-Acetylcyclododecene is an intermediate in the synthesis of 3-Methyl-5-pentyl-2-furanundecanoic Acid which is also known as F5 furan fatty acid. Furan fatty acids are generated in large amounts in algae and fish, but they are also produced by plants and microorganisms. Furan fatty acids are known to exhibit radical-scavenging ability and anti-inflammatory properties.
