Natural Product Identification
Common Name5,6-epetre
Description5,6-Epoxy-8,11,14-eicosatrienoic acid, also known as (+/-)5,6-epetre or 5,6-eet, belongs to the class of organic compounds known as epoxy fatty acids. These are fatty acids containing an oxirane ring as part of the aliphatic chain. 5,6-Epoxy-8,11,14-eicosatrienoic acid is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. 5,6-Epoxy-8,11,14-eicosatrienoic acid can be converted into 5,6-dhet through its interaction with the enzyme epoxide hydratase 2. In humans, 5,6-epoxy-8,11,14-eicosatrienoic acid is involved in mefenamic acid action pathway. 5,6-epetre is found in Mus musculus. An EET obtained by formal epoxidation of the 5,6-double bond of arachidonic acid.
