Common Name20-hete
Description20-Hydroxyeicosatetraenoic acid, also known as 20-hydroxy arachidonic acid or 20-HETE, 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. A HETE that consists of arachidonic acid bearing a hydroxy substituent at position 20. 20-Hydroxyeicosatetraenoic acid is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. 20-hete is found in Pseudo-nitzschia multistriata. 20-hete was first documented in 2005 (PMID: 16258232). In humans, 20-hydroxyeicosatetraenoic acid is involved in mefenamic acid action pathway.
