Common Name15-oxo-ete
Description15-KETE, also known as 15-oxoete, belongs to the class of organic compounds known as long-chain fatty acids. These are fatty acids with an aliphatic tail that contains between 13 and 21 carbon atoms. Thus, 15-KETE is considered to be an eicosanoid lipid molecule. 15-KETE is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. 15-oxo-ete is found in Arabidopsis thaliana. 15-oxo-ete was first documented in 2007 (PMID: 17459323). An oxoicosatetraenoic acid having (5Z,8Z,11Z,13E) double bond stereochemistry, and an oxo group in position 15 (PMID: 19535459) (PMID: 23945567) (PMID: 17910482).
